Hi my name is Paul, I and new to this hobby, I have been a ham for 25 years so I have somewhat a background to radio.My call is KA9UMG. I am working on a Philco No. 81, the radio work with a hum, I change the filter capacitors on the power supply and that took care of the hum.It sounds very good but once in a while the audio will fade away and if you let it set for about a minute it will pop back on, or if you play with the volume or frequency switch I will go back on. I clean both with detox solution but it still happens. Can someone lead me in the right direction.
Thank You
Paul KA9UMG
