Thanks for the offer, Russ!
Yes, possibly. If I ever sell the amp, and I have only thought about it once, another set of tubes might be something that would protect the buyer farther into the future. Even though the amp can use most tubes, Jadis seems to think the KT90 is the best tube for their amps.
I do have a quad of KT90s in reserve, which I was kind of thinking that I would save for posterity. My tubes are getting to the point where I have been looking around for replacements. After about 4 hours or so of playing, I sometimes notice a bit of distortion coming from the right channel at times. I just chalked it up that I am probably getting close to needing tubes.
Actually, I know you will understand when I say this after we found out that we are kindred spirits sonically, and both go for a rich, lush sound, I was thinking the next tubes I should give a go in the JOR would be the JJ EL34. I have a pair of more powerful amps upstairs - my "consolation" for not getting your JA80s(Granites, and they are much better than I could have even dreamed), with JJ KT88, and the sound is great, so I was wondering if I should take the Jadis is a different direction.
My only worry with the EL34 is their ability to drive the speakers, but I will probably end up with a big pair of Frieds down in that system, and they are surprisingly EASY to drive, but you never know.
