Ampeg V7 Power Amp Section - Main preset

Verified · 82/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Ampeg V-7 power amplifier section used a larger complement of output tubes compared to the V-4, likely six 6L6GC or KT88 tubes to push output toward 150–200 watts, making it one of the highest-powered guitar amplifiers Ampeg produced in the V-series. Designed for players who needed full-stage volume from an all-tube circuit without switching to the bass-oriented SVT, the V-7 power stage used a bespoke output transformer wound for guitar-range frequency response. The V-7 is among the rarer Ampeg V-series models and is prized by collectors of early 1970s Ampeg guitar amplifiers.
