RED PCB HACK
If you’ve bought the B-Stock Red PCB you need to run a wire to a resistor to make it work.
The leg of R29 marked in red below needs to be connected to 9V. There are several ways to do this.
The neatest way is to leave a little of the leg remaining when you solder in R29 and R20 (marked in
blue). Then connect those two points with a wire on the back side of the PCB. The hack won’t be
visible when the circuit is boxed.
Alternatively you can leave these two resistors slightly proud when mounting them and connect
with a wire on the top side of the board.
Or you can simply run a wire from the 9V connection on your DC socket to the leg of R29, but that’s
quite a messy solution.
