OMG. I feel like I've just been diagnosed with an unstoppable something something.

V2b's grid leak is grounded via V2a's cathode, a 100:1 divider. There is local feedback.

I remember Brandon saying he really liked the Class Act. He said it had Dumbley qualities and that he gigged with it.

V2a's grid leak is grounded via V1b's cathode, a 100:1 divider. There is local feedback.

I guess you mean V2b's grid leak is grounded via V2a's cathode?

There is also NFB from the output to V2b.

V2a and b can also be viewed as having NFB because there is no cathode bypass.

Whoops, yes, that is what I meant. Will go fix that.

I built one of those for my nephew's graduation gift. That circuit is very aggressive. Had to lower 470K voltage divider after first stage to dump some gain. Screaming Marshall tone and not much clean.
