Default Cambridge Audio A5 Amplifier Repair

Hi,

I currently have a Cambridge A5 audio amplifier that I need to repair as a favour for a community group I do voluntary work for (www.bitfixit.org.uk). There are several burned out resistors on one of the enclosed PCB's. Unfortunately they are so badly scorched/burned I can not read the resistor markings. Does anybody have a set of circuit diagrams and perhaps a B.O.M. as well?

Thanks.

Regards,
John

The circuit is the same as the A500 and the service manual for that should be on here somewhere.

Typically the SAP15 output transistors fail because of bad heatsinking, and they take out the predrivers and bias pot.
