Be sure to have the output of the signal generator as low as you can get it and still hear it in the radio with the volume turned up all the way. The idea is to keep the AVC circuit out of the picture, and it's easier to find the exact peak of a weak signal. You may not even have to connect the S/G to the radio. I find just laying the cable near the radio is enough, and without a direct connection you don't load any circuits that way.

Will do, I am reading up on both 12SK7 and the 12SA7, to see what those little rascals are up to and how they work.
The former owner had this all wired wrong, I corrected some, but will really need to check every little strand of wire right from the top to bottom.
These difficult ones sure are the ones, we learn from.

I have got it now that when I lay the SG line a few inchs away from the loop antenna, I can hear it. So that's working better, I've got to adjust the IF and RF alignment again. The radio was very intermittent, but that is only from the AVG turning on or not, I have learned that the hard way. Being a 60 year old newbie, I find that hands on experence is the way to go, with the help of my friends here on the forms.

Finally finished the radio

Well, I finally finished the radio after many hours of tracing the schematics and learning what IF and RF is. It was six months of pecking away at it, and I'll tell ya, it's a lot of work restoring radios.
Anyways, here it is, plugged in and playing.
I want to thankyou all for the help, without that, it still would not be playing.
I wish you all merry Christmas and a happy new year.
