Hi Ronnie,
When testing your 762 sankyo for sound operation and using a sound film, did you happen to use a stereo sound film or just a mono sound film?
If not, see what happens when you play a 2 track stereo film and try playing just track 2, the balance track, and see if that produces any sound.
The projector may have a problem with the main track magnetic head pickup or associated wiring, but the amplifier could be fine if it reads and plays the contents on track 2 OK.
This has recently happened to me with a Sankyo 702 that I bought on ebay. When I played a mono sound film to test it out, I got no sound from it at all. There was a speaker hum audible but not any of the recorded sound.... a bit like yours Ronnie.
When I tried a playing a stereo film, whilst there was still no sound read from track 1, I was surprised that it played good sound from the balance track or track 2.
So I presume the main magnetic head is faulty or somewhere wiring to the main board while the balance track magnetic head is OK. I am trying to fix this but had no luck yet after many weeks.
