Verified · 85/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Rickenbacker B16A and B16AD are the B16 circuit with tremolo added. Two channels each have a 12AX7 input and their own 500K volume, mixed into a third 12AX7 with a tone-control network between its stages. A fourth 12AX7 is the tremolo oscillator, with Depth and Speed controls and a foot-pedal jack, working on the second channel. A 12AU7 long-tail inverter drives two cathode-biased 6L6s, with a 5AR4 rectifier and a standby switch.
