This looks like it's in nice condition. It's a 1954 Revere S-16 sound projector:

I owned one of these.It ran well and I really enjoyed it until the worm gear went.

It amazing he says the sound is working. I've repaired/restored/resurected three of these (call me a fool) and they all needed extensive amp work. There were several different amps and the circuit diagram on the available service manuals only covers one.

I had to replace all the caps in the amps and rectifiers in one.

They're a fun projector, the amp design isn't very good (probably to avoid licensing at the time) and has high distortion compared to an Ampro Sytlist (another rebuild project).

But they sure look neat running a 1600 foot reel with the extension arm, etc. Almost as cool as the Ampro!

I wouldn't think it would have more than four small tubes. So, it wasn't a standard amp design of that period. Must be a 10 or 15 watter. The cast iron chasis and the stainless steel film transport make it a show piece for sure. If I had more room I would like to have it. [Smile]

It is a "hot" chassis amp. It's set in insulators and there are insulators on the volume and tone control since you could easily zap yourself (remember it pre-dates polarized plugs too).

The amp did use selenium rectifiers instead of a tube for DC and suffers from hum. Also the "volume" control actually changes the amount of light from the exciter lamp.

I'm guessing about the licensing, but back then RCA and WE had pretty strong control over synchronized sound reproduction circuits.
