Hi, the board keeps blowing the 2.5 amp fuse f700. when I remove the capacitor c773 it doesn't.
I have replaced c773 with a new 2200uf 16v but different package size, thinner and longer, but still blows fuse. I also tested three different capacitors inc. the one I removed and all behave exactly the same removed from circuit on a diode test.
I then removed q700, q701 and ic704.
Replaced and tested r711,c726, c727.
With all these components removed and the three others replaced, I have the exact same behaviour, blows fuse with capacitor and powers to correct area without. I have also checked for short circuits in the traces between points, with diode check, all clear....... Any help greatly appreciated! please find image of schematic attached
