I've replaced the PT because the original was dead. New one is made on specs > Primair: 0-230V +scr Secundair: 400-0-400V 0.1A 400-0-400V 0.1A 3.15-0-3.15V 3A 0-5V 4A 0-5V 4A 0-5V 3A 0-5V 3A I replaced the transfomer and neassured voltages, but al are little high now, but the main problem is that there's a hum on both channels. Amp is working but hum is to loud. Anyone an idee what to do? regards Dirk |
