Ampeg VH-140C - Channel A preset

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

The VH-140C is a solid-state stereo guitar combo from Ampeg's SLM era, drawn in 1989 and rated around 140 watts across two power amps. Channel A is the overdrive channel, with gain, diode clipping, an Ultra/Mid control, high, low and volume; channel B has gain, a bright switch, high, mid, low and volume. JFET switching selects the channels, and a chorus board adds stereo chorus with rate and depth plus spring reverb with a separate level for each channel.
