Peavey Classic VT from some time in late 70s or early 80s. Pretty cool little 2×12 combo amp. Does 50W with two 6L6GCs and has reverb and “phase.” Phase control is awesome. PV manual says it “modulates the signal by introducing a variable frequency notch in the amplifiers passband. This phasor is capable of producing an extremely wide range of phasing effects, including tremolo/vibrato effects. When used with a touch of reverberation, it can closely approximate other popular sound effects such as those produced by rotating speakers, etc.”

This amp reminds me of Musicman somewhat since the preamp is mostly op amp driven and the output section has a transistor phase inverter and then tube output section. The plate voltage is only about 500V, which is still somewhat high, but not as high as the Musicmans which go into the 600 and 700V ranges for that extra bit of output power. I was amazed by the Musicman 2100-RD which did 100W with two 6L6GCs, but that's an aside. The plate voltage was 720V.
