This dual mono up to 45 watts in pure class A amplifier incorporates all the unique technical and sonic innovations which have propelled its predecessors into audio legend.

The MkII version allows the use of the KT150 new pentode tube.

The JA30, a pure class A 45 watt per side amplifier, is a very effective monoblock. Each tube is protected by a fuse and is self-biasing even when tubes are replaced, no adjustments are necessary (but the tubes have to be paired). Output tubes can be either KT8,6CA7, KT120 or KT150S and the amps are designed to deliver full power at 15Hz, making for extraordinary bass.

When when switching from KT150 to another type of power tube such as : EL34, 6CA7, KT88 and KT120 a small modification has to be made inside the unit.


The Jadis JA-30, not only are they emotionally engaging, they can also pack some punch. They are pure emotion machine...
