Heh - I just Googled to see if I could find a good link to describe the process and the first link I come up with is a post of mine to the Planet CCRMA list about the problem! My symptom was a horrendous buzz on all 8 output channels. When I took apart the breakout box, I saw a quadrupling circuit on the left hand side of the bottom board (toward the front of the case, underneath the small board that's on top) that had a couple of oozing caps. I replaced them with 2200uF 35v caps from DigiKey: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail?name=493-1879-ND If you've ever done electronic soldering before, it's a trivial procedure: remove the 2 small 2200uF 25v caps and squeeze the larger caps in there. The 35v caps are recommended, it was the underspec'ing of the caps that was causing the problems in the first place. -- ====================================================================== Joe Hartley - UNIX/network Consultant - jh@xxxxxxxxxxxx Without deviation from the norm, "progress" is not possible. - FZappa _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
