Took apart my Cambridge Soundworks 15 Basscube but can't put it back together!

[CuriousGeorge]

I recently had an issue with my Cambridge Soundworks 15 Basscube making a really loud humming noise. When I removed the power board I noticed some burn marks near the solder points of a diode. There were two kinds, one was brown,black, red and gold and the other was red, red, orange and gold. I removed them from spots R41 R42 R43 R44 but don't remember where and which go back where. I can't find the picture I took prior to removal and I've exhausted my efforts of trying to find schematics online. If anyone has this board possibly lying out, if they could take a picture of this corner of the board I'd really appreciate it. or telling me which go where is fine as well. Thank you so much everyone.

P.S. After further research it seems as though it's a good time for me to also replace some of the larger capacitors as well to help solve this really loud humming noise problem that people seem to be having.

Those are resistors and not diodes.

However your loss of the picture does not matter. That board is finished. Burnt resistors are never the cause of failure, but the result of failure. Another component failed and burnt those resistors out. So if you replaced them correctly, the new ones would burn out on switch on.

Those class D amps with switching power supplies are a nightmare to service and not worth the trouble. Hardly anyone published service manuals or schematics now, which makes most things unfixable. That is a disgrace.
