Verified · 92/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The HT-5R is Blackstar's 5-watt valve combo with reverb, here in its original form, drawn in November 2011, well before the 2019 MkII. The Clean channel has volume and tone; the Overdrive channel adds gain through FET clipping stages and both halves of an ECC83, then bass, middle, treble, Blackstar's ISF control and its own volume. A 12BH7 dual triode runs push-pull, with digital reverb, a speaker-emulated output and headphones.
