Canadian GE Model 41 - Mtmattking - 01-24-2025

I think I have discovered why my radio cannot receive a signal.  This comes after re-capping, new resistors and hours spent tracing circuitry.

    . I have no clue why anyone would drill a hole in a tube base.

Someone might have tried to resolder a pin to a wire from the tube. Check is the glass  loose from the base. Check make sure the glass part of the tube is what fits your set someone may have tried to installed a different tube. David

That's an odd tube, it has a tall boy GT style envelope mounted to a seven pin base, it's like someone ordered a 6A7 and Sylvania took a 6A8GT, and rebased it with a base from a seven pin adapter, explaining the brown colour, and the extra hole. Anyhow try resoldering the grid cap, and the grid cap lead on the top, that is a weak point of all of those double ended tubes even more so then the base pins. I would suggest performing some voltage checks on the tube sockets, make sure that everything is there that is supposed to be there.
Do you have a means of testing your tubes?
