Pre XPD PSU Fault

Postby JWvdH » Mon Feb 04, 2019 8:42 am

I have a Pre XPD that gives the following error message, PSU Fault.

I have taken it to my hi-fi shop (no Cyrus dealer) for repair. They replaced some fuses and then the problem seemed to be solved, but after a few minutes the amplifier is running very hot and stops with the same error message.

The repairman indicates that he can repair it if he had the circuit diagram of the amplifier.

Can someone tell me how or where I can get the circuit diagram for the Pre XPD?

Best Regards,

Jan-Willem van der Haar

Sorry, but it's very unlikely you will get one, unless you know an authorised repairer who is prepared to break their confidentiality agreement. Cyrus control access to their circuit diagrams and service manuals very tightly.

Agree with you mojo, I've never heard of circuit a diagram for these mentioned anywhere.
