Two (or more) tube preamps with small bottle tubes like the 12AX7. The big tubes are the power amplifier.I have another question. How is gain achieved on the 2nd channel on these kinds of amps? Is it overdriven tubes or is it circuitry just like an overdrive pedal?
I happen to own what I think was the first commercially produced two channel amp with master volume. Mesa Boogie Mark II-B, I bought factory direct in 1981. It is stupid Cold War era loud. SS rectifier in it:
