Carvin Vintage 33 - Channel 1 preset

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

The Vintage 33 is a two-channel all-tube combo in Carvin's Vintage series of the mid-1990s. Relay-switched channels each have their own volume, bass, mid and treble; Channel 2 adds a drive control and diode clipping between cascaded 12AX7 stages. A 12AX7 drives and recovers a spring reverb with level, and a 12AX7 long-tail inverter drives four fixed-bias EL84s, with a cabinet-voiced line out and a footswitch for channel and reverb.
