hi again, tnx for the replies..i did clean all wafer sws & pots,
didn't clean main tuning cap..have bama prints for rx..will try
voltage & resistance checks..full alignment sounds like a good idea..i
have sig gen..1st & 2nd ifs would be difficult because sig gen calib
not great..i dont think if alignment is my main prob..but will do all
hf aligns..i'm glad to get back into tubes..its like restoring a
classic car, but alot cheaper...hi hi. tnx agn..if u have any more
ideas, pse email me.
