This is full of bumble bees, but there arent a terrible amount of parts in it. Its a hot chassis set. Im adding a few pictures and have a few questions;
1. The crt back side is peeling. Is this going to be an issue and is there anything I can do about it? Hot chassis is one of my concerns with that.
2. The flyback has one crack. The pic looks like 2 but there is only the one. Should this be coated somehow or should I just go ahead and try it after I recap? I did try a slow power up with no results except squeeling from the speaker.
3. If you notice anything else on the chassis feel free to comment. It has a 20W resistor way over tolerance so I know that needs replacing too. The CRT tests good, at least with the tester I bought. I do have a schematic. I also have isolation transformer. I can add pics of if needed. Thanks!

It's a Wells-Gardner built set. A decent set, for an inexpensive model.
The 20 watt resistor is probably OK. The resistance is probably high, because the set doesn't have a UHF tuner. It's a heater dropping resistor. It's either good or bad, they don't increase in value. You mentioned, the tubes light!
I would be more concerned about the high-value electrolytic, as the set doesn't use a voltage doubler. Then you could start recapping in stages.
