Supplied as a pair, each amplifier is dedicated to a single channel, giving the left and right loudspeakers their own separate chassis, signal path and power supply for maximum separation, control and authority.\u003c\/p\u003e\n\u003cp\u003eEach Magnetar mono amplifier uses four KT150 output valves, supported by 6SN7 and 12AX7 driver valves, to deliver 200 watts of valve power. This gives the system the scale and grip needed for demanding loudspeakers, while preserving the dimensionality, tonal richness and fluidity that make high-end tube amplification so compelling.\u003c\/p\u003e\n\u003cp\u003eThe Magnetar mono amplifiers are built with a fully differential analogue circuit, microcontroller-based automatic bias regulation, Fezz Signature Line transformers and a precision-milled aluminium chassis. Premium internal components, including Mundorf capacitors, pure Teflon tube sockets, Neutrik XLR input and high-quality speaker terminals, make this a true statement amplifier pair for the most ambitious two-channel systems.\u003c\/p\u003e\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFlagship mono valve power amplifiers designed for reference-level stereo systems\u003c\/li\u003e\n\u003cli\u003eSeparate left and right amplifier chassis maximise channel separation, focus and soundstage stability\u003c\/li\u003e\n\u003cli\u003e200W output from each monoblock gives excellent scale, control and dynamic headroom\u003c\/li\u003e\n\u003cli\u003eFour KT150 output valves per amplifier deliver powerful dynamics with genuine valve richness\u003c\/li\u003e\n\u003cli\u003eFully differential analogue circuitry supports low noise, transparency and dimensional stereo imaging\u003c\/li\u003e\n\u003cli\u003eMicrocontroller-based auto-bias keeps the KT150 valves operating at a stable, optimised point\u003c\/li\u003e\n\u003cli\u003ePrecision-milled aluminium chassis helps reduce vibration and electromagnetic interference\u003c\/li\u003e\n\u003cli\u003eBalanced XLR input makes the pair a natural match for high-quality balanced pre-amplifiers\u003c\/li\u003e\n\u003cli\u003e2 years manufacturer's warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"hb-fezz-magnetar-mono-pair-panel-2\" class=\"hb-panel\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003ePower Amplifier Design\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eType: Vacuum tube mono power amplifiers\u003c\/li\u003e\n\u003cli\u003eSeries: Fezz Audio Supernova\u003c\/li\u003e\n\u003cli\u003eSupplied As: Pair of mono power amplifiers\u003c\/li\u003e\n\u003cli\u003eCircuit Topology: Fully differential analogue circuit\u003c\/li\u003e\n\u003cli\u003eOutput Valves: 4 x KT150 per amplifier\u003c\/li\u003e\n\u003cli\u003eDriver Valves: 1 x 6SN7 and 1 x 12AX7 per amplifier\u003c\/li\u003e\n\u003cli\u003eTransformers: Toroidy.pl Audio Grade Signature Line by T.
