Joe,
Has the dust settled yet? I mean that literally. The booths I serviced them in were well dusted. Joe hit the nail square on with this review. Its about time that someond did the P35 review. Its funny Joe, but I've had all the same experiences that you have had with them too. Bevan, Now hear this.........Please take all the poo-poos out and put the gears back in!! It was a better projector back then.........

It definitely was! But then Christie couldn't make money off of belt purchases if they did that. There are a lot of Christie projectors out there. Imagine selling 3 belts for each of those one each year. It adds up!

I don't think they changed it to a belt driven design because it was superior to the geared version.

Hey Joe, that "Christie rep troubleshooting manual and FAQ" sure was funny! How did you come up with all does questions and answers?


 


Posted by Joe Redifer (Member # 3) on 08-01-2000, 04:49 PM:
 
Glad you enjoyed it. Some of the answers were based on actual responses from Christie reps. Like the platter LED going bad or out of time. A Christie rep told me over the phone that I must have someone in the booth who keeps messin' with things, and that I should put a seal over the door on the platter tree. This particular rep was under the impression that Christie products could not be at fault (this is where I derived the "our product is not at fault" line from). I was also told by a Christie rep (different one) to just replace the Dolby Digital beasement reader LED when I complained that the LED power supply in the back of the projector didn't do anything when adjustments were made to it.

Others I just made up, obviously.

Hey Joe,
A friend of mine just brought up a good point. You missed a major thing. The shutter and its small size. That "Silver Dollar size makes it very ineffecient. A larger diameter shutter like a Century or Simplex is far more effecient than the "Silver Dollar" shutter in the Christie. My geared P35 is not quite as efficient as a Simplex when measuring light level going through both machines using the exact same lamphouse and screen. I have made these measurements! They had to double speed it(2880 rpm)to get it as good, and it still does not come anywhere near a 35mm Kinoton, or a DP-70 for that matter. That 2880 rpm shutter speed causes all the extra wear and tear on the belts and pulleys contributing to their short life.(Even though I realize I am comparing a Yugo to a Rolls Royce here.) I guess the sum of it all is that it runs but it blows!

Actually I am able to get some pretty good light out of a Christie projector. I agree that the RPM is way too fast and speeds up the wear on the shutter belt, though. I didn't even think of that.

Curtis, what chain do you work for?
 


Posted by Tom Kroening (Member # 201) on 08-02-2000, 01:19 AM:
 
What I never understood is why they don't use a metal timing chain instead of a rubber belt that sheds... You'd think that an oil less projector would be an improvement, but not when its made by christie : P
 
Posted by Kevin Crawford (Member # 469) on 08-02-2000, 01:31 AM:
 
Actually, the older Christies rob quite a bit of light as well. We recently replaced 4 of the old ones. 3 with the Super Simplex movements in them and one of the gear driven ultramittents with used Centurys. Twice the light without replacing anything else. Even if the older ones are better, they are still crap.

Does Christie really believe that they will get people to buy their Digital projectors if they won't support anything "after the check has cleared"? They may buy one or two, but when the fit hits the shan, and Christie won't support them, will companies buy more of them? I don't think so.

It really is too bad that they can build a really good product, ie platter, but build crappy projectors. Worse of all they won't help, or admit that "their product is at fault".
 


Posted by Joe Redifer (Member # 3) on 08-02-2000, 02:46 AM:
 
I did suggest to Christie a while back to try chains instead of belts. At the time I thought I had a really good idea that could improve the projector. But they apparently have already tried that and met with limited success.

The platter is a really good design. But the components they are using now are getting cheap, like the LED assembly. Brand new out of the box shows up as OL (overload) on my multi-meter. I have had three new LEDs do this so far. They are useless. If they could get the older, better LEDs back, along with the fuse-less motor cards, the platters would be unstoppable once again.
 


Posted by Brad Miller (Member # 2) on 08-02-2000, 04:07 AM:
 
Yes, their old LED and speed card design was top notch. At that point the AW3 simply could not be beat. I remember being at one theater for 5 years straight. The first week I got there, I retimed the decks. I would check the timing and resistance every 6 months or so, but in the entire 5 year period, I had to do absolutely NO work on those platters.

Now it's a monthly chore and Christie won't admit their new parts are crap.

I have read Joes reviews now for some time and have been amazed at his lack of knowledge on the products that he reviews. I have kept quiet till now, but I think that in the interest of fairness it is time someone pointed out some of the many errors in his latest review. Without going through each item point by point I will just mention the most obvious. His comments on how hard it is to remove an aperture plate by using the jogger was the first point that hit me, It takes about 3 seconds to remove the rack that couples the plate to the motor, then you can simply slide the plate up and down. his comments on how hard it is to cut the corners square indicate the lack of skill on the tech who cut his apertures, I have cut a few hundred now and after the first few find them quite easy. The problem mentioned with the dowser plates are usually caused by them being incorrectly adjusted and the bottom of the plate is in the light beam for the entire feature. The dusting problems mention are not confined to Christie, and is normally with the early Kodak 2383 stock, Kodak now seem to have solved this. The last point that I think I should mention is the problems with the sound heads. It would seem that Joe is not aware that he is reviewing an early model sound head? That is like a when Ford releases a new model the motoring reviewer reviews A "T" modle, so I think you owe it to the readers to review the latest in the product range and not an old model. The problems mentioned with the airpot were correct, but a simple airpot stop fixes that. With the latest updates I have no problems with the SRD. The comment about the DRAS also leave me wondering, I have not had these problems with the new sound heads, it seems that you have end play in your lateral guides or some other mechanical problems. It is true that Christie have had many problems but I can't agree that they do't offer any backup. We are about 10,000 miles away and can get what we wan't in a few days. Joe also mentioned that Christie will not post in a public forum like this, true, but I have not yet seen Dolby, Kinoton, Cinemacannica, Pennywise and many others responding to this group. My final comment is you should shoot who is ever doing your service and replace him with someone who is even just slightly competent and I think most of your troubles will go away. So Joe, stick to reviewing the film retainers and such as you seem to have a better understanding of these. Regards David

I would like to point out that the infamous Ken (of the Ken and Lonny switch on the SA 10) has posted here before. Check out the CP 650 thread.
 
Posted by Joe Redifer (Member # 3) on 08-05-2000, 02:30 PM:
 
Hmmmmm.... Almost sounds as if Bevan wrote your post, David.

As for the SR-D readers, Christie refuses to send us the update, even though I consistently mention the problems we have been having with the current models for the last 2 and a half years. Since the beginning, they have wanted us to pay for the center pivots. Not gonna do that!

If you read my review, you would have seen that as far as print shedding was concerned, one of the prints in question had MUCH reduced shedding upon going to another theater with different projectors. Please read the entire review next time. Christie always blamed Kodak as well.

It is interesting that I have received many e-mails agreeing with the review, as well as the posts on this thread. So is everybody but you incompetant? My guess is no. You are the only one so far to disagree. I certainly can't please everybody all the time, and that is not my goal. Sorry if the review burned ya.
 


Posted by Brad Miller (Member # 2) on 08-05-2000, 05:32 PM:
 
I must chime in here, as I can vouch for the background on the Christie review.

David, if some company makes a product and it doesn't work and then they make a revision so it WILL work, it should be their responsibility to cough up and admit their first effort was a bust and should supply everyone who purchased the inferior version with the update free of charge. Christie did NOT do that. It is important you understand Joe was not reviewing the Christie projector with all of the upgrades, bells and whistles. He was reviewing what he had access to. Sadly, that is what far too many people have to work with, so in that matter his review is right on target.

If Christie had've cared enough about their customers, Joe would've had a booth full of updated projectors and readers to work with. However, that is not what happened. Christie refused to admit fault on their product, would not replace the defective items, and would not even send one of their own techs out to the site to "prove" that their equipment was not at fault. That is what Joe reviewed. Hopefully Christie will learn to take care of their customers a little bit better or reports like this one will continue to pop up and word will spread. Why would anyone buy a product if it was known that the company did not support even just one of their customers? I certainly wouldn't and I feel Joe's review was justified. Just because he didn't "bench test" the machine doesn't mean that his review was not dead accurate.

Remember, the whole point of his reviews is to test regular assembly line products (not specially tweeked ones) in REAL theaters (again, not a special situation) and to explain how reliable and well the product performed. Customer service and product support is a very important part of that too. Surely you will agree.

Brad, yes I agree with what you say but like Joe I can only speak as we find things, we too have had problems with Christie but have allways had a good respose, I think that they have sent a rep down now on 3 occaions which I am sure you agree is a long way to come and we have always found them willing to supply upgrades when they have been availiable.

Who at Christie have you been talking to? Also, how many of their machines are you running in your chain?
 
Posted by John Walsh (Member # 168) on 08-06-2000, 09:41 AM:
 
I totally agree with Brad. Revisions (to correct design errors) should be added to products.

(A side note: We have 5 year-old projectors that leak oil. The manufacturer says; "All projectors leak; nothing can be done." They've been making projectors for, what, 90 years? This is not rocket science. A design error by one engineer having a bad can effect hundreds of operators for the next 10 years! If your car had some of these defects, you could have more recourse then provided by projector manufacturers.)

A problem, though, is there's heavy pressure to make projectors (and other "booth" products) as cheap as possible. Years ago, when a theater owner bought two projectors for his single-screen, spending an additional $3-4 thousand was not going to break the bank.

Now with a 20-plex, owners try to shave even a few dollars off of everything. And with manufacturers pushing the engineers to get new designs out to capture a shrinking market, mistakes are going to happen, and there no money left to go back and "fix" earlier designs.

As I said, while I agree with Brad, projector manufacture is not a business I'd want to be in today.

Sinplex and Century are owned by the same company, right? (If so) don't be surprised if one of them goes away to save costs.

John,

Nobody is forcing Christie (or other manufacturers) to make projectors so the cost excuse is no excuse. If they or others sell at too cheap a price to make money then it is their own damn fault.

The fact that in the 15-20 years that Christie projectors have been in the Washington DC area and just about all have been removed and canned is indicative of the product and support since there are more than one technician and theatre company at play here (actually there are several and their is a concenus). Can you imagine a Simplex or a Century considered obsolete after just 15 years? There is clearly something wrong here. We just pulled the last P-35 out of service that we had to deal with and it is heading to our "shelf of shame". For such a well designed projector, Christie sure seems to need to make an awful lot of major changes to it. Personally, I think the machining is excellent and possibly the best. Everytime I have changed a part in one, the fit was perfect. I remember checking out the "new" curved gate when it came out in the 80s and pulled a straight gate P-35 out...after bolting the new head on, I just moved the turret over (with the lenses in tact) and aperture plates...and everything lined up on screen perfectly, no nudging was even needed!

The most reliable machines in cinema history have been the gear driven ones and oil bath machines (when kept in oil) tend to have the least amount of parts failures. Why Christie is insisting on the belt driven design is beyond me. I wish Simplex would bring back the gear driven soundhead. Again, if kept in oil (of the proper weight) it will run for decades. And while we are at it, design it with digital sound in mind so it isn't an old mono-optical head with digital stuff kludged in.

John I seriously doubt that either Simplex or Century will leave the market before film does. They both have such fans that Strong would loose sales to another manufacturer (eg Christie) if a purchaser could not get his/her preferred machine. There are those, like me who prefer the oil bath design, while others like the servicability and simplicity of Century. Both put out competent performances. Both can be picked on for their faults and both can be praised for their accomplishments.

I will bet anything David works for a company that is brand loyal to Christie. Surely Christie would pay some help to chains like that but to quote Joe in his review "they might be willing to come to your theater if you are a huge mega-chain who may build more theaters and buy more Christie equipment, but they definitely won't help the little guy." Working for a theater that has since realized it's mistake in buying their projectors I know Joe is not exaggerating about their help.
 
Posted by Pat Moore (Member # 380) on 08-06-2000, 02:32 PM:
 
I don't see any day coming when Strong won't make both the Century and Simplex projectors. Both brands are simply too popular and in demand by those loyal to them from all over the owrld, not just here in the US. Heck, most of the Ballantyne's we build are for special venue operation, but we still make a few for theatres now and then as well.
As I said elsewhere, there has been talk about a hybrid soundhead but we haven't gotten there yet -- priorities.
Allow me to show a little pride: What is a priority for us is service and I think any of you that have talked to any of our customer service people in Omaha, those in the office or those that travel around, would agree with that.


 


Posted by Scott Norwood (Member # 30) on 08-06-2000, 02:45 PM:
 
I'm with Brad and Joe on this one, too. It's useful to hear how the equipment performs in real life, as opposed to a carefully controlled testing facility. Certainly there is plenty of useful information that the manufacturers can provide about suggested maintenance and overall performance, but, at the end of the day, reliability and operating cost are what count.

BTW, with regard to making everything "as cheap as possible"--I agree that this is a problem in the industry, but what about the machines that have been in production for 20-40 years? Are the brand-new Century SA's and Simplex XL variants really all that much different (cheaply built, etc.) than the ones that have been in daily use since the 1960s? I hope not... Personally, I'm a fan of the Century design for its simplicity and "solid" feel, which is not commonly found in the newer machines from other manufacturers. One place where I work has a pair of Century C's which run continue to run beautifully and with minimal maintenance. Will there be any Christie machines left in 40 years? Will parts be available for them?

Carl, The company I work for is large but we are not confined to just Christie,just like Joe I am simply reporting what I have found.

Oh, sure.. I agree.. But you know what I mean; manufacturers are "encouraged" to make them as cheaply as they can. For example, there's no safety-fire shutter on our Simplex PR projectors. It's not really needed; the automation will close the regular zipper shutter when the failsafes drop. I would rather have the safety-fire shutter- it's more foolproof. But they probably felt they could reduce the price a bit, so...

I'm guessing, but bringing back Simplex's gear driven soundhead would cost too much money in manufacturing costs, and would increase maintaince costs. Awhile ago, someone at r.a.m.t. noted that it was probably cheaper (if money is all you cared about) to not maintain equipment and just throw it away after 7 years or so, then to pay (in labor) to maintain the equipment. People have accused car manufacturers of this for years.

Since accounting people (not "showmen") make and run theaters, that the way it goes.

As far as either Simplex or Century leaving the market place, well I'm just guessing, of course. But why would the same company sell two competing products? Even Coke got rid of "New Coke" after a while. Also, if everyone dislikes Christie so much, they aren't really in the running. Cinemecannica is perceived as hard to get parts for (and expensive.) Philips are probably the best value, but are also perceived as expensive.

Accounting people sure don't care about what brand of projector they buy; you could tell them a dog-beater movment was the way to go, and they'd buy it if the price was right. It has already been demonstrated that Americans no longer have "brand loyalty" to car manufacturers (like they did in the 1950's and 60's.) Whoever owns Simplex and Century has a "strong" hold on the market and can do almost what they want.

Also, I don't think modern projectors are made that well. I feel all the machining technology that has been developed over the last 30 years as gone more to making projectors cheaper rather then better. I think that the reason some of those old projectors got to be 40 years old was because they were maintained properly for their first 20 years or so. Then the (good) operators were let go.

But, hey, even though I hated DIVX, I thought it was going to be "the" DVD type format. Glad I was wrong about that one, too!

John, you are absolutely right! Theatre owners look at costs. BUT! They look at ALL of the costs!

Owners also show repair and upgrade costs on their P&Ls each quarter.

Are we talking about real theatre owners, or venture capital types who build on the ragged edge of the margin in order to suck in dollars to finance (or convince others to provide financing) for their next venture?

Believe it or not, there are still one or two guys out there who still build and operate theatres to make a living because that's just what they do.

I work for a company like this. We run Ballantyne because we have become pretty good at keeping them going. They are easy to work on and fairly easy to maintain. They require a little attention, but so long as it is provided, they work.

I've never bought a Christie projector so I can't really comment on this thread.

All I know is that I would not want to be the guy who did this if these concerns with quality and tech support are real.

The big chains could take a lesson from the little guys here. It is a "big deal" when we "buy" anything! The true test comes when we add up the headaches and costs after the purchase.

Anything that posesses moving parts will eventually break (I think that Newton said this *grin*).

How quickly can something be repaired? How much do repairs cost? These are two questions that the "mega-chains" never ask. They are tabulating installation costs for the investors.

I would really like to see a comparison between "theatre chains that have always been theatre chains" and "venture cap people who wanted to make a quick buck" regarding the long term survivability of companies.

Folks, we show movies! Our tools are f&*$%#@! EXPENSIVE!! Even the slightest inquiry as to their maintenance costs (while providing quality presentations), is worth looking at.

We basically deal with Ballantyne/Strong, Dolby, DTS, QSC, JBL, EV, SRT and Component Engineering. We do this because technical support is just a phone call away (and because the stuff usually just "WORKS!").

The companies that we work with all have a Bob, Sean, Ralph, (Lonnie and Ken), or even an "Oscar" who always answers the phone should we call!

Oscar gets quotation marks because he will fix stuff that's a hundred years old!

The "big guys" listen to the accountants who do the install estimates. The little guys are in it for the long run. We just want it to keep going.

John Walsh asked: "As far as either Simplex or Century leaving the market place, well I'm just guessing, of course. But why would the same company sell two competing products?"

It's done all the time:

Ford Motor Company has Lincoln, Mercury, Ford, Mazda, Volvo, Jaguar, Auston-Martin, and Land Rover.

General Motors has Cadillac, Buick, Oldsmobile, Pontiac, Chevy, GMC, Saturn, Saab, Opel, Vauxhaull, Holden.

Chrysler/Daimler has Mercedes, Chrysler, Dodge, Plymouth, and Jeep.

Kodak has MAX, GOLD and ROYAL GOLD films for consumer photography:

Having a variety of brands/models gives the customer choice among a range of features and price.

Let me again say that I don't see a day when we stop making either the Century or Simplex Projectors -- or the Ballantyne line, for that matter. It's not like we don't have parts, you know, especially since we're supporting a lot of equipment that's been in the marketplace for a long, long time. And sales of all three lines is justified business-wise, not just on sentimental value.
Long live the American projection standards.
 
Posted by John Walsh (Member # 168) on 08-08-2000, 07:55 PM:
 
It's true that many companies make and sell competing products within their own company. But, first, a lot more cars are sold than projectors, which makes it worth it. It's also a "personal" market; a person wants a certain kind of car for it's features. Also, a Chevy does not really compete with a Cadillac. Usually, when something is sold in large quantities can this can be done.

Accountants buy projectors; they don't care about features. Since not that many projectors are sold, I would think it's a fairly competitive market. How many projectors were sold last year? One thousand? Car makers lose interest if they don't sell at least 30,000 units.

Here's a question to everybody: Let's say Century and Simplex combined the best features of each. So, it's a semi-already-proven design. We'll call this a; "Cenplex." To save manufacturing costs, let's also say they decide not to make any more regular Century or Simplexs (except parts, and even those cost more.) Parts made in a larger scale for this "Cenplex" would be cheaper, too. Whatever you pay for (say) gate bands would be 30% cheaper. It would be a one-size-fits-all (no 70mm, two-lens turret, etc.)

If they offered this new projector to the theaters for $4000, all things considered, would you buy it?
 


Posted by Brad Miller (Member # 2) on 08-08-2000, 08:53 PM:
 
I would, but I hope Pat would give everyone here on the forum a month to voice their complaints and praise on how it should be designed. I don't know if the R&D costs would be worth it though.
 
Posted by John Pytlak (Member # 331) on 08-09-2000, 05:52 AM:
 
Design and tooling costs to develop a new piece of equipment may be alot more expensive than maintaining the existing tooling for two separate lines. And the new equipment would have to have enough advantages to "win" the hearts and pocketbooks of those who cherished the features of the equipment it replaced.

John makes a good point about the cost of re-tooling. Additionally, Strong will have to continue to manufacture parts for existing Simplex and Century machines. There are just too many of these machines out there for them to ignore.

Semi off-topic question: what is the most expensive projector to maintain over time? Simplex and Century parts last for many years and are reasonably priced in most cases. I would guess that Norelco parts would be on the expensive side, and possibly Cinemeccanica and others, but I don't really know.
 
Posted by Mark Gulbrandsen (Member # 72) on 08-09-2000, 08:24 AM:
 
IMHO it would be Cinemeccanicca, and Christie that would be the most expensive present day machines to maintain. The exchange rate between the US and Italy is piss poor and has almost always been that way. The Christie does not have a field servicable intermittant and they fail regularly making the cost of their machines very high over the long haul. Christie also charges more to drop ship parts directly to a theater adding to the already high parts cost.

Kinoton/Norelco may have high parts cost but they rarely need any parts. Just normal film path parts that are not very expensive, and change the oil regularly. FP-20's and DP-70's are probably THE most reliable projectors ever built. Indeed the Ballantyne projector utilized many of the DP-70's and the FP-20's features. The verticle shaft with gears ground into it from the DP-70, the framing coupler, although for unknown reasons Ballantyne went the plastic route here.The bronze coupler in the Norelco FP series lasts forever. Indeed Norelco/ Kinoton, Simplex, Century, Ballantyne when properly maintained will generally be the most trouble free and least cost to maintain of the bunch.
The key here is to keep the machinery spotless and use a good synthetic machinery oil instead of regular projector oil. Synthetics will lubricate better, last longer and will not break down like regular oil does. LaVezzi oil is a good choice here. Also do not use Lubriplate on any gears, use Super Lube instead.

Posted by Russ Kress (Member # 461) on 08-11-2000, 02:35 AM:
 
Ballantyne uses plastic (actually fiber) gears on the intermittents and shutter trains (Pat, correct me if I'm wrong) to protect the projector's metal vertical shaft. The shaft is "non-field replaceable", and in the event of a component failure, the fiber gears are designed to "break first".

If the intermittent locks up it will stop the machine cold. The shutter (as a result of momentum) will still want to spin. The fiber gear will simply disintegrate (cheap and easy to fix) instead of taking a chunk out of the shaft (send it to the factory).

Century has to be my all time favorite projector to place in the field. You can abuse them for years! While people make fun of Ballantyne oil leaks, I have never seen a Simplex that didn't have a bucket or paint roller tray under it to protect the floor! (LOL)

Of the three, Ballantynes are the easiest to service.

I am still trying to convince an "old codger" tech of ours to post here. I think he eventually will. His name is Mike McKee and when you see him you should ask him how he got the name "Cross-eyed Mike".

He started out hating Ballantynes, but now he likes them.

Hiya;
This is the real Pat Moore, by the way...
Those are delrin gears on the Intermittent and the shutter. We've used steel in various special venue applications, but delrin is in all standard cinema projectors.
Vertical Shaft -- hmm. They can be removed in the field, Russ -- maybe not the most fun thing to do but they can be taken out. In early Ballantyne's the bearing end caps were eccentric, but somewhere in the late 80's we took that adjustment out.

I sort of feel there's a quality vs. labor time thing with projectors. For example, a Century is fairly inexpensive; so are the parts. But it's also fairly easy to fix. Personally, I feel they are also high maintaince (no oil bath.) Their reliabilty is like a Volkswagon's.

I think Simplexes are better, but they are more expensive to buy. Also, they are more involved to repair.

Now, (going against the grain!) I've had very good luck with Cinemeccanicca (V8's and V9's.) They are more expensive and the parts are out-of-sight. Hardly ever had to fix any big problems. But, one time we had to change a shutter shaft on a V8, and holy smokes! What a major job- everything has to come apart. Took all day.

So, what's better? A cheap projector that's easy to fix, or an expensive one that takes all day?

On my previous ramblings: They will probably never get rid of Simplex or Century!

At my past two (daytime) jobs, they made stuff in big quanities. So, reducing anything "redundent" was consitered good. And I must admit, I'm in that same mode. But, it is true that new tooling costs may be more than would be saved than if existing tooling were kept and used.

At one place where I worked, I designed a 19" rack to hold some fiber-optic equipment. There was a question of how it should be grounded to meet the (then new) EEC rules (the equivalent of USA's FCC, UL, etc.) We wanted to meet those rules. It allows you to put the "CE" mark on your equipment, and without it, you can't sell a thing in Europe. All I wanted to do was punch a 0.125" hole in a panel, so field people could mount a grounding stud later (and not have to drill a hole.)

At the design review, everyone was going; "Are you crazy?! That hole will add 15 cents to every panel!" We were going to make about 5000 panels. The accountants had everything figured out to the penny to make the bid and were reluctant to spend the extra money.

John,
Actually the Century is about 1200.00 higher in list price that the equivelent Simplex.
Either will run for many years if properly maintained. One advantage to the Simplex is that it holds allot more oil than a Century can. More frequent oil changes in the Century and keeping the gear train clean and lubed with Super Lube will contribute to its long life. I advocate synthetic oil and lubes in any situation as they have better lubricating properties and are simply better in the long run.
Either machine can have problems. The Century if not maintained properly WILL have more problems than a Simplex do to no oil bath. However there are the small fibre gears in a Simplex intermittent that do shear if there is a serious film pile up, or if the movement locks up. These are in reality mechanical fuses so the rest of the gear train does does not suffer the same fate.

Getting back to the earlier part of this thread...........

I too work for one of the worlds largest cinema chains as David Johnson does (I used to work with him but that's another story!). We use Christie, Kinoton and Cinemeccanica as our main brands but also have just about everything else made in the last 30 years.

We have had a few disasterous Christie installations (5 Ultramittants in 12 months), but some very solid ones too. One Christie, located close to me, has never skipped a beat in 5 years and it is in a remote projection booth with little daily attention other than cleans and threads.

As a large chain we continue to purchase from several manufacturers in projection and sound (Dolby mostly but also DTS and SDDS). The absolute keys to running ANY equipment is professional installation and most importantly experienced, dedicated projection staff. In most of our locations in this country we now have at least one projectionist with 20 years plus experience.

I will always hire and train people who are interested and dedicated to the craft of cinema projection. Film has a lot of life in it yet. The biggest single thing that any cinema can do to improve their presentation is have a projectionist who knows how to clean (lenses, port glasses, mirrors, film path, platter rollers, payouts) thread-up consistantly, understand what screen presentation is and maintain the equipment(dolby tone once per fortnight, oil & belt changes general adjustments).

And Oh, one very important thing, check the auditoriums once per shift for sound level, temperature and a patrons view of focus.

A Century costs more than a Simplex? That seems strange. I would think that the oil bath design would make it cost more.

I can't stand it when I have a nice theory all worked out in my head, but then someone wrecks it using actual facts! Darn...!

I guess we all have to pay for ORC screwing the Century up. Strong had a big job ob its hands when they took it over.
