#1: power supply. No +/-15V voltage.
Recapped the entire supply, no voltage.
Then I tried to replace the Roland 022-86C (100-120V) transformer with a Triad Magnetics toroidal transformer that delivers +/-15V, still nothing. Wondering if anyone else here has done work on one and what the typical points of failure were my were, perhaps the L723DC / LM723CN?? Or the 2SD-324 voltage regulators? Nothing is burnt out, and I’ve definitely got the winding correct.
Got any other ideas? Thanks,
Todd
