Ed, appreciate the help very much. You're right! One IF adjustment was off, way off. Using the scope with the probe connected to the 6H6 2nd detector, pin 3 plate. I was able to peak all 4 adjustments spot on. This improved dial calibration. More on that later. Bottom line, it had to be effecting the AVC as you stated. Funny, using the grid of the eye tube has been suggested many times by many folks. I'll have to check this against my Philco's, and see if I get the same results.

Again many thanks Icon_wink

Renovated Radios do carry what you need. As for the voltage, a wire should be at least 300V-rated.morzh — 11:13 PM
