Let’s walk through the schematic like a signal tracer. With a copy of the diagram in front of you, follow these stages:

The JC-120 is essentially two independent 60-watt amplifiers in a single cabinet. This "true stereo" design is critical for its signature sound. Roland - Global Dual-Channel Preamp : The schematic features two distinct channels. (Normal) is a straightforward clean path, while

First introduced in 1975, the circuit has seen multiple revisions, but its core philosophy remains: a pristine, transparent clean tone that acts as a perfect canvas for effects. Roland - Global Architecture and Design

Attempting to repair a JC-120 without its schematic is like navigating a city without a map. Here is why:
