[QUOTE="Iain Glass, post: 382086, member: 255368"] Can anyone help with my power supply? Output voltages are high 50v instead of 30v, 12v instead of 8v. Obviously to do with feedback circuitry? Voltage correct on C10 and C11. Changed IC1, IC3, all capacitors on primary side. System switches on, registers 1000 then channel number. After 15 seconds goes into oscillation, trying to switch off and on. Power switch has no effect. [/QUOTE]
