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?
