Philco model 51 problem
#1

Gentlemen,
I am currently working on a 1932 Philco model 51. I have changed all the capacitors, most of the resistors and checked the tubes. Sometimes when I apply power the radio will not play. The only way to get it to operate is to momentarily short pin 2 of the oscillator and 1st detector tube (# 224) to ground. Then it comes alive and operation seems to be normal. I just discovered this by accident when I was checking voltages on that tube and it is very repeatable.  Works every time. I understand that this radio has some weird characteristics but this should not be required to get it to play. Anyone have any ideas to solve this problem??  thanks
walt
