From the post
Here is a layout for the Rockett Flex Drive.
You can find original thread and schematic here.
The layout has already been verified by Gavin (Hozy31).
Gavin said: "It seems biasing the drain to 4.5v is not the way to go. You need to turn it until you get decent volume on all switch 2 positions"
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.
