Just the video I was looking for! I scored one of these (well sort of, it's a Filmosound 156V but the circuit appears virtually identical besides using a field-coil speaker) for $50 awhile back and have been planning to convert it into a guitar amp, but the jam-packed nature of it (and figuring out how to rig up replacements for those damn rectangular multi-section can capacitors) has definitely led to some serious procrastination. Hopefully now I can find the motivation to move forward with it! Also, I'm pretty sure the extra 6V6 is used as an oscillator to drive the exciter lamp in the projector, but don't quote me on that.
Glad to hear this might inspire you to get going. Once you get those big multi-section caps out, things open up a lot. Also, the partitions can be removed to make more room. There were also some big molded dot-code coupling caps that are space hogs - I wanted to keep them but they were splitting from age or heat or both. Out they went. Having a field coil would be cool!!
I had a few of these, they are nice little amps, but i preferred the German Siemens & Halske (Klangfilm) amplifiers. They were build like army equipment during those days.
@@muttamps The Siemens projectors were popular in the Netherlands, almost every school had one. it was easy to find them until a decade ago. The Bell & Howell projectors were more scarce overhere the ones i had came from the army. I guess most people got rid of the projectors, scrapped them, not aware there was a useful tube amp attached.
Do you have a Filmosound? Want one? Let me know what your experience is below!

I've seen some of that gear, definitely well built!
