Hi All
I am about to start my next build. It is going to consist of some circuit re working. The basis is the Hoffman AC30 schematic. What I am planning on doing is this. I do not want to have two inputs. I only want to use the top boost. But instead of eliminating the normal input (consists only half a triode and volume) I want to add it to the top boost as an additional gain stage.
My question about plate voltage is this.
Can I use the same source of plate voltage for two tubes? Meaning, run the the plate voltage from an existing tube, in parallel with my added stage?

yes
