Marshall AS80R - Channel 2 preset

Close · 66/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The AS80R is Marshall's 80-watt solid-state acoustic combo from the mid-1990s, the larger sibling of the AS50R. It has two channels for instrument and microphone, anti-feedback control, and onboard reverb and chorus. The power section is stereo: a pair of TDA1514A power amp ICs, each fed from its own op-amp driver, drive two 10-inch speakers, one with a tweeter, so the chorus can spread across both sides.
