Looking inside the 12-28 there is a single busrail that runs across the channels with a connection from the power supply board. Turn the mixer on, measure the voltage on the busrails….. this will make sure that you have the right one! Then just disconnect the feed from the power supply. Tape up the end of the loose wire so that it does not short on anything and there you have it. :)
