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

The 5B3 is an early-1950s wide-panel tweed Deluxe with Microphone and Instrument inputs. Two 6SC7 octal dual triodes, one working as a paraphase inverter, drive a pair of 6V6GTs on a 5Y3GT rectifier. It gives a warm, loose tone that breaks up early.
