Jadis Orchestra Reference bias adjustment?


I would be very grateful, if someone could explain me (in easy terms),
How to check and adjust the bias setting on my JOR with KT-90 tubes.

Hi Mcfarland,

thanks for your post. It would be great, if perhaps
you could email me those bias instructions.

Thanks a lot.

At the price Jadis sells this amp, it's a shame that they don't provide for either self-biasing OR user-friendly adjustments like a good number of less-expensive offerings...

Apparently, there are somehow inconsistent views about how often the bias on the JOR needs to be adjusted.

While most owners here at Audiogon feel adjustments are necessary every few months, one dealer in Europe says, adjustments are only needed once every 4 -5 years due to the fact, that Jadis only uses selected and well burned in power tubes.

Jadis in France says, the JOR needs no bias adjustments at all, unless power tubes are changed.

How often do you owners adjust your JORs if you don’t change output tubes?
