Fender Vibrolux Reverb AA270 - Normal preset

Verified · 92/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Vibrolux Reverb AA270 is an early silverface Vibrolux Reverb, a 2×10 combo with Normal and Vibrato channels, each with volume, treble and bass and a bright switch. The Vibrato channel adds 12AT7-driven spring reverb with a 7025 recovery stage and 12AX7 optical vibrato with speed and intensity. A 12AT7 long-tail inverter drives two 6L6GCs for about 35 watts, and its 5U4GB rectifier runs a slightly lower B+ than GZ34-equipped versions.
