Re: Alesis IO2 USB audio interface re-capping

Thought i'd join/post as i found this post quite helpful

Ive just fixed 5 of these IO2's (for a studio)
All had the problem with the signal clip being lit up as soon as you plug it in.
I found on every one, the component U9 had failed! (after 6 hours of probing)
thought id post this up as i couldn't find a fix any other place!
Checked the service manual, U9 is a:
IC VOLTAGE INVERTER CHARGE PUMP UNREG TPS60403 SOT23-5
got mine from:
