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

This Carvin model represents a mid-period revision in the brand's solid-state amplifier line, identified by the revision suffix indicating an updated design iteration. Carvin frequently revised circuits during production to improve noise floor and reliability. The amplifier delivers a clean, neutral tone typical of Carvin's direct-sales professional amplifiers of the late 1970s.
