From the post
Schematic and info HERE
I added the" Low Mode" as well hence the additional Mode switch.
And by request, a layout with a Klon buffer before the main circuit.
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 Dirtbox Layouts. No KiCad fragment has been drawn for this circuit yet.
