I replaced the 1 meg resistor and re-connected the cap wire circuit on the 6r7 1st audio tube. I have 89 volts at pin 3 on the 6r7. The 1st & 2nd IF tubes(6k7's) 247 volts pin 3, 84volts pin4, and -4.5 pin 5.
The voltage at resistors is -15.4
I cleaned the tuning condesor and blew the dust out of the IF coils but it did not help the squeal. I will have to see if I can get my hands on a signal tracer. Ebay maybe?
