I'm building a PP 2a3 amp right now and haven't decided on the input
stage. I'd like to use 6J5G and/or 1626 valves. Open to other
suggestions, but like to keep to octal or UX5 types (I also have 76,
37, 56, 27). I'd also need a differential first stage for the option of
balanced or SE, and I have CCSs. 2a3 needs about -50v of bias. Ideas?
