philco 41-280 volume control
#6

Hi,
If I ground out the diode plate (pin 6)with the green secondary wire from the IF can it is dead quiet.No audio is heard at any volume.
If I ground out pin5 the audio is reduced but still there. If I ground the blue secondary wire from the IF can the audio is low but still there.
I even wired  in the volume control circuit from a 42-360 and still cannot mute the audio when the pot is turned down.
