V1 triodes question
« on: July 24, 2022, 11:38:11 am »
Is this possible and are there any issues with this? Each triode is a different circuit.

Look at the Deluxe Reverb schematic.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

i'm more asking about the plates and B+ supplies to them. Vastly different plate voltages on v1a vs v1b for my requirement.

Nothing unusual about that.
