The tube socket pins that go to the plate of the audio output are the highest rate of intermittent noise since these are the hottest pins in the radio with the exception of the rectifier tube.
The Philco phenolic sockets from the early 1930's are terrible; they need to be cleaned and bent for tight contact. Don't rely on contact cleaners when dealing with audio plate contacts; they must be cleaned manually.
