Gibson EH-195 - Microphone preset

Verified · 86/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The EH-195 is a pre-war Gibson amp with an AC/DC supply and a field-coil speaker. A microphone input on a 6SJ7 pentode and two instrument inputs each have their own volume, then a 6J7 stage feeds treble and bass controls and a 6SC7 phase inverter. Six 25L6 beam tubes run in parallel push-pull, rectified by four 25Z5s with series heaters, and there is an echo-speaker jack. A note on the sheet covers wiring in valves for vibrato.
