Hello Tom,
I have the exact same radio that was my Grandparents,has not run since at least the 1950's. I have replaced most of the capacitors so far. All tubes were checked on my tube tester and some replaced(6F6G power tube is showing bad),but lights up. When checking it so far it only has the same low hum out of the speaker. I noticed two of the thread like wires from a small choke coil are broken off.This will need replaced or maybe I can re-attach the wires? Long shot probably.I have about the same limited experience,so we are both here with the same problem. I am using a Ryder schematic.I am studying it more in depth.I have three electrolytics(2,6,8mfd)to replace yet. There are four leads coming out of the can.Is one a ground for the can?
The 12mfd electrolytic started to boil up and put much voltage to the Rectifier(5Y4G).It was fine when I replaced that one.
Hopefully your post will get some answers........Lee
