I've been replacing capacitors on this chassis, so far all the electrolytics, and several wax/paper.  I found and replaced a 1,000 ohm, 10 watt resistor shorted out, Part no. 39371-5, and item #13 on the schematic.   I have also tested all the tubes.

Initially, before any repairs, I could get no sound at all from this set.  Now, after the above mentioned repairs, I get a slight hum when the power is on,  and then, when the power is turned off, I get a distinctive louder hum which quickly diminishes to nothing.??

I'm new at this game, and don't have any test equipment except an ohmeter and a Precision 912 tube tester!

Any thoughts or suggestions would be greatly appreciated.

Dave
