This is turning into quite a project. The reflector behind the bulb cannot be polished, it's a rear coated glass lens, where the silver coating has deteriorated badly.

I ordered a chemical kit online to re-silver the mirror. Will be interesting to do and to see how it turns out. Additionally, a few small rollers are absent, so I have to machine new ones. The whole mechanism needed cleaning very badly, I used tons of q tips and isopropyl alcohol.

I also figured out that if I change the projection lens to one with a longer focal length, I can put the projector into an adjacent room, with a small window to let the picture through, and eliminate the noise of the projector almost entirely.

Haven't even opened up the amplifier yet, but that's much more in my comfort zone so not too worried about it.
