I've recapped this radio and tested the resistors and tubes. When I bought it the filter caps were replaced with new caps but one of the terminals on the filter can was still hooked up. I corrected that and rebuilt the 4 bakelite blocks and now there's no sound. The radio did play earlier and rather well considering the only caps replaced were the two filters. I took pictures and checked the pictures as I went and nothing stands out.
I went back over looked for a mistake but I don't see anything wrong. I also went over every solder joint that I made to be sure it wasn't a bad connection. I took the voltage of pins on the output tube and measured;
Pin 2 = 6.26VDC
Pin 7= 17.5VDC
Pin 3 = only 1.15VDC
Pin 4 only 1.41VDC
Voltages on the rectifier (5Y4G);
Pin 7 = 374VDC
is there something obvious that I'm overlooking ?
