I own a PL DiaLogue Premium Integrated that's about 7 years old. It's in daily use 2 to 4 hours per day. Several months ago the a couple of the 12au7 tubes became noisy, and I decided to replace all six (6) of them. I went with General Electric JAN stock from Upscale Audio - and opted for premium grade a/k/a "Kevin's Stash." They've been wonderful - dead quiet. Not cheap but well worth the money, as far as I'm concerned.
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.
