Title: CSP325 buzzing Post by Skip on 05/01/26 at 20:46:19 I can't get the AI help desk to work so thought I'd try here. I'm getting an annoying buzzing out of the right channel of my CSP325 pre-amp. I've tried swapping the two output 6N1P's around. Changed out the 6N5P and the 5U4G tubes. No change. Buzzing only in the right channel and out of all four input settings, Front, A, B, and Mute. Any help mucho appreciated. Skip

I had a one channel buzz once that was because an unshielded interconnect was too close to a power cable that was running parallel, not crossing at right angles.
