Re: Repairing Alesis M1 Active mk2 Monitor Speakers

Joining the blown up M1A620 club. A pair of these were 'gifted' to me not working during Covid shutdowns. One required a C8 replacement and now works fine.

The other has been troublesome. After C8 replacement the power supply seems good with
High rails at 36.8V and low at 17.25. When all hooked up, the woofer pulsed a very loud square wave type sound. Original woofer got toasted by this prior to my ownership.

I removed the LM3886 for the woofer and the tweeter side seems stable without it...
