DuMont RA-112
Sounds like that you are well on your way. Don't forget to provide an output transformer if you use one of your audio project speakers. The speaker lead from the RA-112 provides B plus to tthe output tube and the output transformer is mounted on the speaker. I use carbon comp. resistors for replacement in older sets. Metal film does not hold up well for higher voltage drops and they are inductive. Removing the two tubes removes the high voltage and the B plus from the vertical stages as well.
