Hi y'all, hope that you can give me some direction. I have a Philco 46-1203 radio/record player that I re-capped several years ago. It's played great for me, but recently a bad hum has begun intermittantly, both in the radio and record player. Playing with switches, the on/off on the turntable, the front on/off or the tone knob can get rid of it for some seconds then it's back. After the set warms up, about 20 minutes, the hum is gone and it plays fine after that.

Could you give me some starting points to look?
Thanks,
Alan
