Schematic
This is a board layout, a drawing of where each part goes, and the post may link the schematic it was drawn from. Open the layout at Tagboard Effects. No KiCad fragment has been drawn for this circuit yet.

Check before you build · 4 values the reader of this layout was not sure of
- 200u electrolytic left of centre: printed clearly, unusual value
- 2u electrolytics (three, lower middle): printed clearly, unusual value
- 250p and 30p ceramics: printed clearly, unusual values
- 100K count (15) on a very crowded board: several overlap links and each other, could be off by one
