From the vendor

Lovepedal's Englishman, voiced after a cranked vintage AC15/AC30. It is a single 2N5088 transistor booster derived from the EHX LPB-1, with a gain pot in the emitter and diode clipping to ground after the gain stage. The three-way Fail switch picks silicon (1N4148) diodes, BAT46 Schottky diodes or no clipping. The post notes it differs from Lovepedal's COT 50 designs only in the transistor bias and larger input and output caps.

Fixes to the schematic, from the post

  • Clipping diodes D1 and D2 are labeled 1N9148; they should read 1N4148 (a 1N914 also works).
Check before you build · 1 value the reader of this schematic was not sure of
  • D5, the series power diode, is drawn with its part number as '(?)'.
