Verified · 90/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Rect-O-Verb 50 is the first-series (1998–2001) 50-watt Rectifier with spring reverb: the two-channel Dual Rectifier circuit stepped down to a single pair of 6L6s with silicon-diode rectification. Clean and Lead channels bring Rectifier gain to a power level better suited to clubs and recording; the Series 2 of 2001 revised the channel modes.
