I made an embarrassing newbie style mistake on this project, and not on the projector itself, but the electronics!

After giving the amplifier a careful recap, I set out to evaluate performance... Since it has a field coil speaker I didn't disconnect it when I was checking the amplifier with a signal generator. I blew the 70 year old Jensen 12 inch field coil speaker! 10 seconds of turning it up a bit with 100Hz fed in was all it took.. Coil came loose and now it sounds like crap... Been a while since I did something that dumb.
