Verified · 89/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Rickenbacker B410 and B212 are the guitar models of the mid-1970s B-series, built on a 1974 "B Series Guitar Amp" circuit with 4×10 and 2×12 loadings. Two channels each have treble, bass and mid, a bright switch and their own volume; the second adds a FET tremolo with depth and speed and a 12AU7-driven spring reverb. A master volume and slave out sit before a 12AT7 inverter driving four fixed-bias 6L6GCs from a solid-state rectifier.
