About product

DESCRIPTION

This dual mono up to 45 watts in pure class A amplifier incorportes 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 6550s or KT88s 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, KT90, KT120 & 6550 a small modification has to be made inside the unit.

About brand

Jadis Electronics

Encouraged by this success, he decided in 1983 to rationalise his production and participate to the fundation of the JADIS Company. In the beginning, the amplifier was manufactured unit by unit, from the original plans, but quickly Mr Calmettes turned out his own technicians, who were able to produce electronics in accordance with his philosophy.

The quality of these amplifiers is, for the most part, provided by their output transformer. With an original conception and being as good as indestructible, it gives the amplifier absolute stability, whatever the load may be. Entirely made within the JADIS Company in Villedubert, it is wound by hand and then it is poured into a special resin, guaranteeing maximum soundproofing and thermal stability. As for the power, the specifications are amazing: the maximum acceptable power is 2500 W before saturation.

Being the only ones in the world which respect these specifications, the JADIS amplifiers give fantastic dynamics as much in the bass tones as in the higher trebles. They present a total lack of coloration, and most of them work in pure class-A.
For these reasons, it constitutes the ideal amplification system for all acoustic speakers, whatever the impedance curve, the type of functioning, or the efficiency may be.
