Sound City Sound City Pa200R preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Sound City PA200R was a professional public address amplifier head, offering 200 watts of output across multiple channels for front-of-house or monitoring applications. Dallas Arbiter built these to the same standards as their guitar and bass heads, resulting in a PA amp with unusually musical character that found its way into many professional touring rigs of the early 1970s. Its multiple inputs made it adaptable for vocals, keys, and other instruments beyond guitar and bass.
