MOTM

Finished putting together my first MOTM module, the 120 Sub-Octave
Multiplexer and power supply.

Input A works fine, no problems.

Input B doesn't seem to work in Cross Mode.  I've checked the wires to the
jack and there is continuity to the board.

Since Input B doesn't work when in Cross Mode I'm wondering if anyone has
any advice on further troubleshooting this problem.
