I've been restoring a Philco 42-350. I've replaced the rotten rubber wires, all the wax caps and about 90% of the resistors. So the radio plays very well on all bans most of the time. But the push buttons and broadcast bans will randomly stop working. I can restart both bans by touching the plate (pin 2) of the XXL mixer tube with my voltage meter. This works every time and the radio will play normally (for awhile). Could this be a problem with the Mica caps or my Oscillator coil?
