James,
for fun I am going to put a bias box on AGC, try clamping it and see if that does anything.
I will check the values as you described. I "think" the fix of the 3rd IF tube is working now, but I have to try it a few more times to be sure.
The agc was acting 'funny' as I was not able to distort the pic or break sync when set to max CW, the new 3rd IF seems to have fixed that.
Oh an I did not do one of the things I promised myself a while ago, always scope the AGC voltage. Look for horz hash or any thing other than a nice DC voltage.
Meters dont catch this so a scope is a must. So will be scoping the AGC voltage as well.
