Ok, i have a cab that was wired for jamma and i am now putting a 60-1 in it. i want to yank out the taito power supply and put in a switcher. i am okay with the whole bob roberts ac diagram, but the isolation transformer that he has only has two wires in and two wires out.
how can i determine which wires to provide power on the iso transformer? there are 6 brown/black wires on the input that have jumpers in the molex (upper right of the power supply board). on the output side, i am ok as the white wires attach to the molex where the black wires come out for the monitor. (upper left of the power supply board). all of the red/yellow, etc on the output side go to pcb. thanks
