Jadis Orchestra Reference bias adjustment?

Pierre will talk to you for an hour about the Jadis line. I think he realizes Jadis expects him to make sure their product is understood by newcommers to Jadis. Besides Jadis' exclusive rights to making the finest tube amps may be slightly altered here in the US once Cayin makes its way to the US shores. Thats yrs off, but indeed will one day be competition for Jadis.

I've had mine for 4 yrs now and sounds the smae as the day I turned it on. I don't know much about biasing. I guess the tubes have 2000 hrs, but as I say they sound like the day i turned it on. btw I use the bass and treble tone controls up 98% of the throttle. What I've found the tone controls have basically 2 modes, off/on. Only at 90% open do the tones open up, at 95% open there is some slight notice. At 98% is the only way I like it. I love dynamics, and anything less is not acceptable. Also at mid open on the tone the amp sounds very flat and lifeless.
So i guess if you bias from the inside, you get the same effect as pushing the tone controls up to 98% open. Only at 100% do i gut a hum from the amp. btw I lsiten at low volume, 1/4th to 1/3 vol open. After 1/3 I get much less stability /dynamics from the amp. Maybe the speakers are too much a load against the currect for the amp. The speakers are rated 87db. . But still, at 1/3 vol open, i get plenty of music to fill my 30X40(with open hall ways on everyside) cathedral ceiling room. The music carries throughout the entire house. So maybe with low vol I use the tubes will get a longer life. btw Pierre mentioned the Jadis stock tubes are quite expensive, so replacing will be a major cost. Which i have no plans to do for yrs to come.

Trelja what label 88 are you usig? I bought a quad of Electro Harmonix 88 (EH88) and sounded like c**p. Seems not all tubes are the same. I may try the JJ77's I've heard good things. Or JJ88's, or both. Keep one sell the other.
