Hello, it looks like my Mudbunny board is from an erlier version. I would love to use a 3pdt switch board to wire this up. The pads on the board say sw-in-gnd-out. On the left side of the board is the 9v and gnd. Where does the wire from the SW pad go? Transistors are Russian KT3102 which is why they are backwards. I also used all mylar and Russian kd521 diodes to give it some original character.
