I am a newbe, whom aquired a Philco Model 50. When I received it, the volume control was in 2 pieces. I aquired a used one from the U.S. I installed it the exact same way as the old one, making note of the wiring, as a dual potentometer. Problem is, that I have no noise (not even a hum out of the speaker). The filliament voltage is ok, all tubes light up,the tubes test ok in a tube tester. I have replaced all filter caps, as well as all paper caps, and checked all resistor values.Only resistors and caps I did not replace, are the enclosed ones .I checked the B+ voltage, and it is 317 volts measured at the filter capacitor to ground. The output transformer measures 354.0 ohms, and the voice coil 1,195.0 ohms. Can anyone give me some advise, or steer me in the right direction. Thanks
