I finished the recap and cleaned the variable cap contacts. It's working fine on the lower bands A, B, C, and D, but I'm still having problems on bands E, F, G. The oscillations die on the left 1/3 of the tuning dial

The tubes check good and I've swapped them with known good tubes for the heck of it - no change.

All the resistors measure 10-20 % high, but I figure that's OK. I'll check the coils and trimmer caps next I guess.
