Defy 7
100 Watts Tube Power Amplifier - Bi-Wired

|
|
JA 30
The JA30, a pure class A 30 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. Output tubes can be either 6550s or KT88s and the amps are designed to deliver full power at 15Hz, making for extraordinary bass.

JA 500
A larger, more powerful and flexible version of the JA200, this amp delivers 400 watts of class AB push-pull power. Flick a switch for 250 watts per side of quasi push-pull triode power, giving the listener the choice of unlimited, earth-shaking dynamics or less power with added smoothness and refinement. An additional feature is the anblization of the power supply with tubes.

JA 80
The JA80s are self-biasing and sport outstanding tube protection circuitry and fuses, with a LED for each tube to signal malfunctioning. Sixty watts of Class A power per channel avoid any trace of crossover distortion and, with soft, graceful clipping, appear to deliver even more power.

JA 800
The JA 800 is finest and most powerful amplifier. To get this extraordinary level of sheer power and musical refinement each channel has two chassis supporting the monoblock power supplies. The six chassis JA800 represents the world class statement in amplifier design. The two chassis can be bridged together to yield an 800 watt output per channel or used in hi-channel mode for two separate 400 watt amps per channel.

SE300B
Aficionados of single-ended triode amplifiers now can enjoy Jadis quality and performance with this 10 watt pure Class A set featuring hand crafted output transformers with plenty of headroom. Two 300B output tubes, two 5R4WGY rectifiers, and Jadis' painstakingly precise design and manufacturing standards make this the preferred amp for mid-to-high efficiency speakers. Like other Jadis units, the output transformers are hand crafted by Jadis without any gap in the magnetic circuits, and are used well below their full possibilities (they can be used on 250 W amplifiers). It is important to have a large output transformer because a direct current crosses the primary in this construction, which in a push-pull construction the direct current in the transformer primary cancels itself out.
