1930? General Electric T-12

[legenbass77]

I got this radio from a relative to fix for them. Cabinet is in great shape, as well as the speaker cloth. The only repair I can see is the 10uf electrolytic capacitor. I've never opened up anything this old. Tested the tubes, and the only weak one is the 80 rectifier. The wiring looks ok, hooked it up to the isolation transformer, and it came to life. It actually works pretty well, nothing smells like it is burning, but has a slight buzz in the background. Also it just has two wires dangling for an antenna. I have a schematic for it too, so I've been getting familiar with the components in the chassis. Looks like there are 2 metal boxes with capacitors inside that probably need to be replaced. Has anyone ever worked on one of these radios?
