Did I just read that right? So is the Pro35 (a projector most here ridcule) and the DP75? My DP75s have a drain hose and I can tell you how much oil is in the intermittent at all times...what is your point?Steve PS...the Ernemanns leak too (as all oil based machines will eventually do to some extent) ------------------

Steve,
Indeed the Pro?-35 and the DP-75/FP series have similar oil level indicators. In the case of the DP/FP series this is a 500.00 molded plastic tube with cap that is at the top of the intermittent. In the case of the Pro?-35 its a nickle worth of cheap plastic tubing. Both however serve the same purpose. I am hardly comparing the two from a quality standpoint though. At any rate its better than not having one as on the Ernnemann.....actually I might take a Pro?-35 over an Ernnemann.Gord, The Pro?-35's don't give much grief till either the Star wheel breaks off, the coupling and outer bearing fails, the shutter gear fails or when it is seal and "O" ring replacement time. Then it is much grief and mess! Oddly the Pro?-35 is an FP-20 ripoff in some respects. It just wasn't done correctly. At any rate the technician is going to make bucket loads of $$ on any of these repairs.

Trivia on those hoses with the plastic cap. At one theatre I managed, the projectionist dutifully checked the oil level on the DP75s without thinking about the plastic cap, always found it perfect, and was unpleasantly surprised when the intermittent seized. The cap prevented the true level of the oil from being determined at a glance. Just like water will stay in an inverted cup, the oil remained in the tube at the original fill level. I mention this because, like Steve, this fellow thought he could determine how much oil was in the intermittent casing by looking at the tube. If caps are used, a substantial hole should be added to them to break the vacuum. It might slightly increase the amount of leakage, but that is better than replacing a dry intermittent. Another problem with this type of "window" on the oil is that the oil in the tube always looks fresh and clean. Most of the other comments you guys are making are above my head, and you probably already know of this type of problem, but I add it for others who might not.

I can proudly state that all of the Kinoton's I deal with have their caps removed once put into service or ventholes placed into their caps. Furthermore, filling through the drain hose will prevent sizable air bubbles from giving a false indication....Many a time a tech or an operator filled the intermittent only to find that the level dropped later in the day but no oil puddle....the air bubbles finally came up and the true level was had. Gord, as to Kinoton's having features that you may not like...I think I can safely say that EVERY projector has features that someone may not like. If I really wanted to be mean, I could rattle off some on the more complicated Kinotons but on the PK-60D...you have a VERY simple projector, mechanically...very little to go wrong. Since the gate and soundhead are good, the machine performs well in the presentation department too. You want a beef with the PK-60D as it comes out of the crate? Here's one...they make you PAY if you want a gear reduced inching knob. Thus far their solution has been a "POS" aka position button to step the motor down slowly though it doesn't really work well for setting the intermittent stop for threading...their latest, hot off the press, solution is to make the knob bigger! :-(...They should just get over it and put a proper inching knob on all of the "D" projectors.
