Recommendatons bias settings for KT88 and KT90
Hi Guys,
I've been droping in again as I have some time and ideas. Even if my amps sound good, after awhile you still want to do something different and start taking them apart again. LOL I was hoping to get some opinions about the "sweet spot" for KT88 and KT90's. I bought a set of both. PP 4x power tubes at AB1 with B+ 425V. I want to run a bit rich on class A if possible. What sounds best with a descent life span? BTW, I also got some NOS EI 6CG7's. Wow, what a diference a tbe makes! Thanks, Wessel |
