One solution i the use of KT150 in UL with 1627I'm interested in building some sort of single-ended triode tube amplifier, probably in a mono power amplifier format. I know enough to know that 15W is a lot to ask of a SET amp, but not enough to know how feasible or infeasible it is. If my expectations need readjusting, then please, adjust away.
This is a circuti I used
the E88C is a single triode

This is the frequency answer at 10 w with 6 dB od Feedback
There is a resonance at arount 200kHz but is not significative
