Now get out your BAG#3 from the wire bag and we will
install the red and black wires that will be used as the B+
(High Voltage) and corresponding Ground wire.
These pictures show the red and black
wires installed in the B+ and GND
holes on the M2 power supply board.
On the right you will solder the red
wire on the B+ from the topside of the
board - clipping off the remaining lead
- and do the same for the Black GND
wire.

This section controls the voltages that we will be supplying
to the analog output board.
Here we are configuring for 12V filament operation (as used
in the L3 Line, L3 Phono, and DAC2.1 Level C).
