Chas, that is great info, not just on tube rejuvenation, but using the transistor radio to check for oscillation in the RF Section (I have not had that issue but I have 1K resistors in the ones that burned out) and using the transistor to check for effective RF gain. (I have a Grundig digital all wave that I have sometimes used to pick up IF to check for a working converter.)

So far, I have not had a TRF give me fits, I guess I am lucky.
