Default Cambridge Audio A500 Left O/P Fault

Hello, I have been reading through the forums for quite some time looking for a solution to my problem. I have learnt a lot but sadly havent quite figured it out yet, if there is anyone out there who could point me in the right direction it would be greatly appreciated.

My friend has kindly given me a cambridge audio A500, for nothing! i soon figured out why it was free but all the better really, tis an interesting challange. Only the right o/p is working, i've done a few tests which i've noted below;

(testing done when warmed up)

SAP15 (u201) - reads over S and E - 11.9mv
(u202) - " " - 11.9mv

(u205) - " " - 13.5mv
(u206) - " " - 13.5mv

o/p right at rear - 11.5mv
o/p left at rear - 4.6mv

i've also done some resistance tests over the transistors comparing left to right and they all seem ok. Sorry for the lack of info guys, still at college but learning fast.

Any ideas? more testing?Schematics for A500
