General Electric M113YRD

Opened it up and the aquadag coating was completely in tact. There appears to be only one white .1uf 1000v ceramic-paper cap on the 410v boost source. The single electrolytic can runs stone cold so I wont be in any rush to replace it for now, good thing too cause it looks like a real pain to get to. Robert1 you're certainly right about the heat this thing gives off. Those compactrons give off a TON of heat. They even got too hot to touch in the brief time it took to test them! I'm currently running it with a small desk fan pointed at the vents and things are staying pretty cool now. I haven't replaced anything yet, but I have noticed that there is a large disk cap on the cathode of the damper tube that's bubbled up a lot. Could this be the source of the picture warp I'm experiencing?

Also, (not that it's important for any practical reason anymore) the UHF tuner appears to be stuck a little off from channel 66. Turning the tuner stem (still missing the knob) has no effect and it doesn't stop in either direction. Is that by design or is there a mechanical failure?

Gotta say, I'm still pretty impressed with this set. I know everything inside is really flimsy, but GE's goal for this model was to make it as light and compact as possible, after all. And they certainly succeeded, considering it weighs a mere 12lbs - about as much as my modern tabletop flatscreen tv of around the same size.

Your UHF tuner has a limited slip clutch - the inner shaft/outer clear knob will spin continuously, but the outer (larger diameter area) shaft/channel indicator will stop at channels 14 and 83. I just verified this by placing the knobs I have on a similar tuner to see the effect.

The pix shows the two knobs on the tuner - and an antenna I suspect is close to what you need. It's actually for a same-period Sanyo tube set, but will work with slight differences. No modification should be necessary, but the new antenna doesn't have the shoulder on the rod like the old one, and sits flush with the top of the ball, rather than 3/4" proud of the ball. GE was the only manufacturer to use a combination shoulder-and-short rod arrangement, and JFD only manufactured them for GE, so Russell and others didn't offer an exact replacement. All my GE and JFD stuff is the longer rod, which won't fit/stow in a small set like yours.
