Hiwatt SA115 Custom 50 Combo - Brilliant preset

Verified · 84/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Hiwatt SA115 uses the same 50-watt, two-EL34 Custom 50 circuit as the SA112 but in a cabinet with a single 15-inch speaker. It keeps the Normal and Brilliant channels and treble/middle/bass stack, while the 15-inch driver gives a deeper, rounder low end than the 1x12 version.
