Spent some time cleaning this today, it was a smokers set.
I just blew off the chassis with compressed air, I'd really like to give it a bath but don't want to spend that much time with it.
Cleaned inside the cabinet with spray cleaner and rags, horribly, horribly filthy, did as well as I could without taking it apart, looks pretty good.
I replaced 8 tubes with stock I had in my caddy, the only one I didn't have was a 6DX8.
Sprayed all the controls & tube sockets with DeOx, put the cover back on the tuner, it was off when I got it.
Repaired the cracked-in-two VHF dial with super glue.
The worst problem I found was a peaking coil that had fallen apart, the round coil part was actually hanging below the cabinet where it had fallen through the vent holes, one end of the wire was broken off, I don't know what function it affects but it couldn't be good to have it busted.
I repaired it but it's missing a few turns of wire.
I washed the yoke with soap and water, the set fired up but i hear a slight sizzle so I'll have to let it dry for a few days before doing any more work on it.
The zip ties on the convergence assembly are my doing, it was originally held together (factory) with some type of tape, long since deteriorated so that was the quick fix.
