Selmer Zenith 100 - Channel 2 preset

Verified · 83/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Zenith 100 is a 100-watt valve head from Selmer London. Channel 1 has an ECC83 input with treble, bass and a 1M volume; channel 2 has an ECC83 input into Selmer’s push-button tone selector and its own 1M volume. Each channel gets a second ECC83 stage and its own reverb Depth control, and a 6BR8 drives the spring reverb with recovery and a footswitch. An ECC83 long-tail inverter drives four fixed-bias EL34s from a silicon rectifier.
