Great, thank you for the quick reply. I'll give it a go and let you know how it went.

Hi all,

I saw in the forums a fix for the common Alesis Mk2 power supply capacitor issue, and I was hoping I might be able to get some help on a different power supply issue.

I was recently given a pair of Alesis M1 Mk2's. Only problem is the written input on the back panel is 120v and we run 240v here. I've got a transformer but I don't want to use it, especially since it doesnt have a ground input.

Looking at the power supply, I noticed that there is a jumper (J4) next to the power switch jumper that reads "120/240".

Tracking...

Hi,

i've visited this site a number of times for its very useful info, but now i find myself in need of more. I can just about wield a soldering gun without hurting myself and others, although that hasn't stopped me from attempting to cobble together various hardware projects along the way.

i'm a control systems engineering nomad, currently residing in the middle east.
