I have a 40-190 that is running a 5Y3 rectifier and an aftermarket power transformer that is under rated even for the 5Y3. I can fix all of this.

But all the Riders and Beitman schematics I'm looking at show a 7J7 Det.-Osc. tube. Mine has a 6J8 in it and everything associated with it looks original. Is the 6J8 original and is there any schematic showing it? A lot of different connections and component differences between the two.

Thanks,
Pepper
