Default Marshall Avg150h Problem

Hi everyone, I have a problem with an avt150h I was wondering if anyone could help me with. The amp powers up fine without the 2 power boards (with the TDA7293's) connected but when these are connected either the 2a fuse blows or the tracing on the top of the pcb from one of the filter caps (c221) glows (this happened the 2nd time I replaced the 2a fuse but the fuse never blew this time) I obviously havent tried again as i dont want to totally knacker the trace on the pcb (I have run a continuity test on that particular trace and it seems fine..if not a little scorched) the weird thing is I know for certain that the power boards & Chips work fine as I have several avt150's here and have triple checked the boards in the other amps.....

any help pointing me in the right direction would be great
