my first post here, so hi all!
I recently purchased an opus 3 which seemed to be all fine, but now i discovered 2 (maybe one?) problems. it makes a steady humming noise ( i guess the psu?) and it tends to give a crackling noise out when the brass section is on, on the left output, mono and stereo. i already downloaded the service manual, would like to here from you where to start debugging the thing, cheers kristian
mmh, wondering if my question is not clearly or noone is reading it ?
