Hey thanks for that. I swapped speaker cables and the scratchy moved with it. My spares were Primaluna and the noise vanished. So,, replace my spares now. Voodoo
Primaluna signal tube replacement
I need to replace my small signal tubes in my 2 year old Dialogue Premium. The 2 middle tubes are good. I had replaced those with GL 12au7. The outer tubes are stock Primaluna. Left channel got “scratchy” and I replaced with some backups.
Do I go cheap? Doesn’t affect audio quality,,right? Or pay more for longevity? Love the amp and it’s on a lot. Thanks for your advice.
