I don't have subs for the 1st and 2nd IF, tried the 3rd IF and RF amp, and made no difference. I will try an external AGC supply next to see if I can make it increase gain to the overload point. Maybe some parts values have gone wonky in the AGC. I am also ordering some tubes for the tuner, IF, and AGC.
