Hello Everyone,

This is my introduction post as well as a restoration question post. I've been an antique collector for some years and 'specialize' in antique desk fans. Just yesterday I got this 60MB with a near-mint Shellac container from my capitol city for $40. Since then I've watched a couple series on this type of restoration as well as browsed this forum for some answers. I plan on really only restoring the electronics to make them safe. As for the cabinet, I like the shape that it in and only want to clean the original finish. Now, I'm going to try to diagnose what the issue is with this radio and you all can tell me if I'm way off.

When plugged in the radio has a deep humming noise. It is not affected by the volume control, so I assume it is an issue with the electrolytic capacitors. Besides that, all of the tubes light up. So, my first idea is that once I replace the electrolytic capacitors and other paper covered capacitors, I'll have better chances. As for the action of replacing these things, I would put my knowledge at very basic. I can generically read a schematic, and have very little experience with capacitors, so any tips would be very appreciated.

Thank you all very much...
