JADIS ORCHESTRA

I own a JOR and love it, with the caveat that retubing power tubes requires setting bias voltages usings pots that are inside the unit and I definately rate that job as being not user friendly. The smaller signal tubes can be rolled to your preference and do not require bias adjustments. The unit sounds stellar on my Harmon Kardon Sixty's, but only average trying to push my Martin Logan SL3's. Give the Jadis an easy load and you should be quite happy with the sound. A qualified tech should be able to fix the cap without difficulty (and bias the output tubes) and there should be several in your area who might service tubed guitar amps for local proffesionals. Happy listening,

I use KT 90's because they came with my unit, along with a spare new set of them. They sound deep in the bass end, and I like the midrange too, although I have not tried any others. Apparantly the Ei factory which made them had a fire and no longer produce them, and I am told the EH 90's are not the same in sound quality. The above has been most informative. Thanks, and enjoy your amp.
