it works ok but the fan doesn’t kick in, it’s supposed to on start up for a second to test it then it comes on when it gets pushed and warms up. It’s doing neither. So it’s either the fan relay that’s gone (which I can’t find an exact match of at the moment to replace) or the signal to it, or the temp sensing part of the circuitry.
It’s a shame as it works ok apart from that and the person I am trying to fix it for can’t afford a new (even 2nd hand) amp so he’s amp less at the moment.
