Multivox Premier 120 - Chan 2 preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Premier 120 is a two-channel valve combo from Premier, the amplifier brand of New York's Multivox; this drawing is dated January 1961. Each channel has two inputs, its own 12AX7 triode, Volume and Tone. The channels mix into a 12AX7 phase inverter driving a push-pull pair of 6V6GTAs from a 5Y3GT rectifier. Tremolo comes from a 12AX7 oscillator and a 12AT7 modulator stage, with Strength and Speed controls and a footswitch jack.
