Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

This is the 70 W version of the Fender Bassman Ten combo, from the CBS era (Fender/Rogers/Rhodes), with a Normal channel (with Deep switch) and a Studio channel. Two 7025 preamp tubes feed a master volume and a 12AT7 long-tail inverter driving two 6L6GCs, and the amp drives four 10-inch speakers.
