Mark...you preach and preach....and yes there ARE installation of digital cinemas...but by and large, those that were hired to do these big conversions...have been laid off...to say the "conversion" is at a trickle pace is an overstatement.

As to switcher power supplies...all of my installations have a spare on site and we rotate them through so they all age. I have NOT found them to gain any longer lamp life and more often than not, shorter. While the frequency is indeed high...you can always tell a lamp run by a switcher...their anode surface has a very fine grit surface...kinda like a piece of sandpaper. I still install brute-force supplies unless there is a need or specific reason for the switcher...they are more reliable, period.

On the switcher's up side...they are less expensive (you can ofen buy three switchers for the price of two HR rectifiers...especially if you factor freight in). Switchers are also VASTLY more efficient on power conversion. Running 150A DC on an IREM N3-180 (a bit over 4000-watts), you would draw upwards of 35A per leg of 3-phase...the same lamp could be run on an IREM EX-170 for about 22-23A per leg. That is over a 30% savings on electricity alone. Your infrastructure also drops as #8 wire drops to #10 wire for requirements...Step down transformers within a complex can be smaller...and on and on.

I like the ability to remotely control the current in a swither over a HR in some applications too. There are a lot of things going for them...field service isn't one of them.

As to Louis and not replacing CAPs in IREMS...I've had a couple caps in newer IREMs fail (shot their cookies out the vent hole)...note, the current generation of N3 series have better filtration than the previous N3X series. (or G3 vs G3X for console types).

It isn't too uncommon for me to change capacitors in a HR rectifier...if I see a lot of "snot" on the anode of a xenon lamp after "normal" hours...I change the caps...clears right up and the lamps last longer...pretty simple.

Now as to $400 pullies....are you a dealer? Really. I've never had a problem with that one and we are MOSTLY a reel-to-reel installer. On Simplexes, the pulley has been a zero cost option too...not $400...after all the pulley lists for under $100 and the is the only part that is added (plus short set screws to affix it). Also, don't use roundthane...you'll never get an even pull...use a V-belt...cheaper, better, longer lasting.

Steve,

You may want to stock up on your fav. HR rectifiers... they won't be around for more than a few more years... and yes, if more studios jump on the VPF bandwagon that Paramount initiated this week then yes the installation of D-Cinema gear will be something that you and I won't be able to keep up with.

I agree on changing out caps but having the right gear and know how to measure the level of ripple is also something one has to have... Ripple/inrush meters have not been manufactured in nearly 20 years. Ya can't JUST judge by looking at the anode or cathode... it may have been running that way for quite some time. A ripple/inrush meter and high power resistance standard and storage scope are all necessary to do the job right and when it needs to be done.

As for Strong, they are dying a slow death and it is obvious to all involved in this industry. Soon all they will have to offer will be screens and service are those are not going to support them for very long, nor will the small percentage they make off of distributing NEC projectors.

Mark, can't you measure inrush with a current probe and a DSO?

So, if STRONG is playing the 'demand of the masses' game, what are the ones like us that have these old black suitcase dinosaurs to do when they let go .. buy their competitors rectifiers?

I've noticed that their interest in the repair exhange department took a dump in the river for some off reason...

I do have a non-reactive shunt very similar to what Osram used to send out to test inrush. I also own one of the very few ripple/inrush meters ever built and it's quite accurate. Since I collect-restore test gear I am very fortunate to also own a number of calibration standards and am able to verify my own DMM's, scopes, freq counters and so on for accuracy on a fairly regular basis(Isn't E-Bay a great place!). There is also a place here in SLC that can verify those standards if need be.

I didn't intend to diminish John or his plight, I only offered a probable reason for the policy change. And, I do believe I qualified my rant with:
quote: Tim Reed
Not that you are guilty of this, John, but it hurts me to hear the badmouthing and the childish name-calling of my company by some on this forum..
I also said that I was not speaking for the company (read: IMHO). That, dear friends, is ALL I was bitching about, because I could just *feel* another bash-fest coming on.

Btw, thanks guys, for your consideration.

I certainly don't mean to bash Strong, but Tony: UPS 3-day Select is good customer service? Umm, not over here it's not. And in this industry that uses next-flight out shipments as frequently as it does.

(I'm spoiled. Our FedEx discount is such that FedEx priority overnight is less than a dollar more than FedEx Express Saver (3-day). After all, if it goes on a plane, it's not as if it is in the carriers' interest to warehouse other people's stuff).

--jhawk

John, with all the trouble I'd had with Strong in the past I was pleasantly surprised that they did do 3-day. UPS' rate for a package that big (and heavy) is really steep, and I know for a fact that you are spoiled with your Fed-Ex deal, as there is a HUGE price gap in UPS' rates for Next-Day and 3-Day services.

Now as to $400 pullies....are you a dealer? Really. I've never had a problem with that one and we are MOSTLY a reel-to-reel installer. On Simplexes, the pulley has been a zero cost option too...not $400...after all the pulley lists for under $100 and the is the only part that is added (plus short set screws to affix it).
Yep, that was the standard charge for the take-up kits added to the 5-Star at the factory. I was not the dealer, so maybe it was the deal (such that it was) that my dealer had at the time. I do know the charge was from Strong, not my dealer.

Tim, I'm glad you see the posts here in the context of our individual experiences with Strong, and not any reflection on you personally or your working with Strong.

I for one do lament the fact that for whatever reason, there are those at Strong who have made decisions that have had very negative effects on their customer service, and to some extent, the quality of their products.

As Mark has pointed out (in some other threads), there has been some positive things they have done (for example, the porosity issue with the XL projector head castings, I do agree that the main casting is better than the old ones, but whoever came up with that hideous framing handle needs to be shot), but there have sadly been more negatives than positives from them.

As for the old black switchers, I have found them to fall into three categories;

They flame out within the first few hours of operation;
They last for quite a while, but when they did fail and Strong repaired them, they kept failing over and over again;
or like the one I now have on my own projector, they run seemingly forever. Mine has maxed out the little "mercury" hour meter and it's still going, well Strong.

When it dies I'll be sending it to Mark. [Smile]

Tim,

On a completely different note:
If he still works for Strong, say hello to Tim Ellwell or maybe it's Elwell; I can't remember and I just moved 18 prints [Frown] . He used to be the Cineplex Odeon/Loews-Cineplex tech for the Northwest. Good guy.

"Reports of my demise are greatly exagerated!"

Film definately has a present and a future, probably alongside some form of video.

National Amusements (parent company of Viacom/Paramount) is our customer. They do not have a single stand alone video screen.

Carmike alone owns the majority of Dig. Cin. installations (2100 about). Most are stand alone. 'Nuff said. Louis

Sorry to drag up just an old thread but I wanted to say two things

1. Tim, I much preferred working for Chris Peirce, Charlie Achee, Frank, Bud Shepard, Andy Lizotte and everyone in Louisiana (and around the country) at NCSC. To be fair I did not stick around STS for too long.

2. I thoroughly enjoyed working on the booths Louis supplied for NA and working on his automations and other entertainment engineering/Hadden equipment.

NA had some of the better booths but some things made me laugh. Louis, Remember Glenn Terell and his phantom surround speakers?

Now back to your regularly scheduled program...

I tried to buy empty 8330 cabinets, but JBL wanted to sur-charge us for a special order. We had to be one of the only places that had spare surround speakers installed in plain sight! (Architect's requirements.) There should have been no rattling cones anywhere in that circuit.

Many thanks for the compliments. Especially nice in retirement.
