Re: Repairing Alesis M1 Active mk2 Monitor Speakers

Thank you for replying so quickly Khron, I appreciate it.

1) I've attached some photos, hope it works, not used this forum before. There was a load of gunk there that I cleaned out (didn't realise how much I'd scratched the board until I took the photo... *facepalm*).

2) Sorry, was way too vague there wasn't I. I tested them using an ESR meter.

C8: ESR=0.31ohm, Vloss=2.0% and 342.3uF
C35: ESR=6.8hom, Vloss1.2% and 1081nF

Forgot to say that the C8 cap is 330uF...

Re: Repairing Alesis M1 Active mk2 Monitor Speakers

Hi guys,

Hope someone can lend me a hand here! My mk2s blew a few months back and I've finally gotten round to opening them up. Bare in mind I'm a complete novice when it comes to electronics.

I can see a trace that's burned off so that's an obvious fix but I'm stumped as to what else may be wrong. I've tested the c8 and c35 caps and they seem fine to me so I started testing other components in the hope that I'd stumble across the fault. This is probably a silly way to go about it but I'm not sure what...
