Poss. OSC Problems Philco 34
#15

Hi All;
I have it receiving signals from the Generator at 600KC, 700KC, 1100KC and 1400KC on the Broadcast Band..
BUT, I found out that the Oscillator works on these frequencies ONLY when I have my O'scope probe attached to pin 4 of the 1C6..
Go figure ???
IF, I attach my probe at the 2nd Detector then the signal comes in but a few points lower of the scale..
Attaching the probe at the 1st AF it moves down another point or so..
So, do I need to put a Capacitor on pin 4 of the 1C6 to compensate for something that the scope is doing to the oscillator circuit ??
Would possibly a Gimmic wire make the difference that I need ??
THANK YOU Marty
