G'day! I have seven CE2000 amps (they are great!).

One of them failed at a gig on the weekend. Visible symptom was major overheating due to fan not running (heatsinks are now slightly discoloured). The fan tested OK so I pulled the main board and visual inspection shows there are two resisters (R7 and R1) fried with charring of the PCB underneath.

I'm a somewhat capable repair hacker (I have an ancient electrical engineering degree) but I'm wondering if it's even worth trying to do a trace and repair. Has anyone else seen this fault before? Is it worth the time and effort to find the schematic and have a crack at fixing it, or is it easier/cheaper to just get a new main board?

Any advice appreciated...

Thanks!
Laurie.
