Carvin Vintage 50 / Nomad 112 / Bel-Air 212 - Drive preset

Verified · 86/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Vintage 50 is a 50-watt two-channel Carvin tube amp from 1994. Relay-switched channels each have their own volume, bass, mid and treble; Channel 1 is clean, and Channel 2 adds a drive control and diode clipping between cascaded 12AX7 stages. A tube-driven spring reverb, an effects loop and presence follow, and a 12AX7 long-tail inverter drives four fixed-bias EL84s, with a cabinet-voiced line out and footswitchable channel and reverb.
