I have completed a kit with PS02 2xJ99,2xA12,4xN72, and chasis. Separately all of them sound ok. When all of them are in the chasis, I have some hum specially in the N72. When I disconnect one of the J99 or one A12, everything is fine. Here in Europe AC is 220 volts. Should I upgrade de PSU to PS03. Everything is as indicated except for the API where I am using some Forsell op amps, with the SC op amps I have the same problem.... :idea: :?:

It sounds like an upgrade to the PS03 might address the symptom. Please e-mail sales@seventhcircleaudio.com directly for details.
