Thanks Mike, I did as you suggest, leave the grid cap on and also tuned sig. generator up and down. I may not have went far enough the first time, because I found the signal way up at 216 ! Strong signal too, definitely not a birdie!
I thought maybe not having the 3-tube shielding might affect, so I faked it with tin foil. No difference.
Dial isn't off by much, but is off.
Perhaps I caused the IF Peak to move by removing and cleaning the Var. Cap.
I will attempt to move it back to where it belongs 175 kc.
-Simon
