HH Scott 222B preset

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

The H.H. Scott 222B is a stereo tube integrated hi-fi amplifier, not a guitar amp, with two identical sides. Each has a two-stage 12AX7 phono preamp, a 12AX7 tone and loudness stage with bass, treble and scratch filter, and a 6BL8 driver and phase splitter feeding a push-pull pair of 6BQ5 (EL84) tubes with global feedback. A 5AR4 rectifier, stereo/mono selector, balance control and centre-channel output complete it.
