A small aux board, setup for doing DC heaters, or a regulated DC supply for any type of use. (E.g. 5v MIDI chip supply)
The heatsink makes it perfect for 12v heaters, the board is essentially the DC supply setup I have on the main PCB’s but carved off into a small form factor.
The hole spacings are deliberately sized for hanging off the end of a Marshall ST1 board.
PCB is 80mm x 45mm.
