Gibson GA-95 Apollo - Normal preset

Verified · 85/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The GA-95 Apollo is a 1960s Gibson combo with Normal and Reverb channels, two inputs each, and loudness, bass, mid-range and treble controls plus a bright switch on each channel. The Reverb channel adds spring reverb with a level control, and a valve tremolo has frequency and depth, both on a foot pedal. A 12AU7 drives four 6L6GC tubes in fixed-bias push-pull through a driver transformer, on a solid-state rectifier, into two 12-inch speakers.
