@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.
I have 3 Bell & Howell projectors, one like yours and two late model ones. One has a plastic gear bad. I have an Elki, and an Ampro. The Ampro is well made with all metal gears I have a Bell & Howell Jan projector. It has dual motors for projection and rewind with all steel gears . It was made for the govt. is built like a tank, cost thousands new,and has no resemblance at all to the conventional Bell & Howell school projectors. If you want a top of the line 16mm a Jan is one of the best.
Another thing. Does yours have that odd size plug for the external speaker? Mine has this bizarre plug... it's just a little bit smaller than a 1/4" headphone jack.
Was it designed that way so you can only use a Bell & Howell external speaker, or was that a standard plug size in the '60s?
woohooo...awsome

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.

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

AWESOME!
The inside is exactly like my B&H 545 Filmsound Specialist!
Mine was made in Canada though.
These old projectors are litterally built like tanks.
Can you make a video of that older B&H? I'd like to see the inner workings of that one.

Woah, a Zenith cassette deck? I hope that's going to get its own video!
