@legoman6986 The 500 series manufactured up to1969 used tube amplifiers. Starting in late 1969 B&H switched to transistorized amplifiers. The model number will have a "-T" indicating transistor amplifier. The 1500 and 2500 series are all transistorized.
Looks good that one. I've just today got my hands on a 1692 projector... and it had a part of that worm gear fallen of, i've managed to insert that part again using super glue. Do you got any more info on that worm gear problem and how you might be able to fix it, or at least give it some more time to live. The projector otherwise is almost as new... it's incredible how well it has survived (if you dont count the worm gear x) )
You may want to short the huge motor starting capacitor terminals when working inside the back cover to avoid a nasty shock. We usually had to change the 25C5 tubes in the push-pull amp about every year.
Thanks for the great video. It brings back old memories of my high school days when I ran the same model projector. Especially enjoyed the video of the inside back cover.I will never forget the time that the lamp imploded probably because the fan belt stuck and formed a bubble on the lamp. Glass shot everywhere with a puff of smoke, but the projector wasn't harmed at all, just had to shake the glass out of it. That was almost 40 years ago. Look forward to seeing more of your projector videos.

@Sunsetdrivein did most early projectors use the tubes, or are there better B&H projectors out there that don't use the tubes?

Look out for that motor start cap, it'll wake you up if not discharged!

Those 25C5 tubes get hot! Plus they go bad from vibration of the projector motor.
