My preamp is making noises. Any Ideas why..? 6 months old..
I’m getting “scratching , popping” noises in the speakers. Even when the system is muted or on pause..
The noise comes from out of nowhere and, will last only about 5 to 10 seconds , then goes away..
So I rolled the Tubes (2) - 12au7 .. I have 3 sets of Tubes , and all 3 sets made similar noises..
So I swapped the Power Cables, and RCA’s, (not the culprit)..
I removed the preamp from the system, running only the OPPO 205 to the Odyssey Amp for 2 weeks..
No noises, at all.. IS IT THE TUBES ..???
