I have this cute little 14 watt per channel no feedback amp thats finding its home as a computer speaker amp. Originally intended as fully class A push pull at 10 watts according to the load lines, but I’ve found it runs a bit into AB with a bit more power. No feedback at all, save the concertina phase splitter. Bass/treble is a passive stack. Im considering adding a mono sub out post tone/volume of course, and having trouble deciding how to implement it. I’m not afraid of feedback at all, just wanted to keep this one feedback free. Have already committed sin with the concertina (and no longer matters)? Would it be sacrilegious to consider using op amp techniques or local degeneration to kill unwanted gain? Just wanted to take the pulse of what others might do. It will mean adding another tube, unless option 1 is chosen.
I have it wired for 12 volt versions of preamp tubes at the moment. I have plenty. Power stage is 10EM7, and I’m making octal/novar adapters to use 10GF7 which I’ve gotten a larger quantity of.
