Description
The Jadis JA80 MkII is the legendary monoblock tube power amplifier that launched Jadis in 1983, functioning as the brand's enduring flagship statement. Operating in pure Class A with an autobias triple-load push-pull circuit, the MkII version expands pentode compatibility to include KT150 tubes alongside KT120, KT90, KT88, 6550, and EL34 options (internal modification required when switching between tube types). Its phase-inverter and driver stages utilize double triodes (ECC82 and ECC83), supported by an oversized power transformer, high-capacity voltage filtration, and AC filament heating with noise-reduction balancing. Built on a non-magnetic 316L stainless-steel chassis with hand-wired point-to-point construction and silver-copper solder, the JA80 MkII features Jadis' iconic lifetime-guaranteed output transformers (matching 1 to 16-ohm loads) and dual speaker terminals for bi-wiring, delivering an exceptionally natural, dynamic, and musically immersive performance.
