Each amplifier uses two directly heated 300B output tubes and proprietary toroidal output transformers, with a separate chassis for each channel. The redesigned signal path is designed to preserve fine tonal detail while delivering a spacious stereo image, a richly textured midrange, and smooth high-frequency reproduction. This version features the Moonlight (silver) finish.\u003c\/p\u003e\n\u003cp\u003eRCA and XLR inputs accommodate different preamplifier connections, and speaker terminals support 4Ω and 8Ω loads. Automatic bias regulation maintains the tube operating conditions without manual bias adjustments, while a warmup delay circuit protects the tubes during startup. Black tube cages are included, making the pair a practical foundation for a dedicated tube-based stereo system.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePair of mono vacuum tube power amplifiers for separate left and right channels\u003c\/li\u003e\n\u003cli\u003eParallel Single-Ended architecture with dual 300B output tubes in each monoblock\u003c\/li\u003e\n\u003cli\u003e2 × PSVane 300B L UK Plus power tubes per amplifier\u003c\/li\u003e\n\u003cli\u003e2 × 6SN7 UK Plus driver tubes and 1 × Genalex GZ34 rectifier tube per amplifier\u003c\/li\u003e\n\u003cli\u003eProprietary toroidal output transformers\u003c\/li\u003e\n\u003cli\u003eRCA and XLR inputs\u003c\/li\u003e\n\u003cli\u003eSpeaker connections for 4Ω and 8Ω loads\u003c\/li\u003e\n\u003cli\u003eAutomatic bias regulation and tube warmup delay circuit\u003c\/li\u003e\n\u003cli\u003eFrequency response: 6Hz–38kHz (−3dB)\u003c\/li\u003e\n\u003cli\u003eTHD: less than 3% at 1kHz and full power\u003c\/li\u003e\n\u003cli\u003eDamping factor greater than 10; input impedance: 50kΩ\u003c\/li\u003e\n\u003cli\u003eDimensions: 420 × 380 × 226mm per amplifier\u003c\/li\u003e\n\u003cli\u003eDesigned for use with an external preamplifier\u003c\/li\u003e\n\u003cli\u003eSupplied as a pair with black tube cages\u003c\/li\u003e\n\u003cli\u003eFinish: Moonlight (silver)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat’s Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2 × mono power amplifiers with specified tube complements\u003c\/li\u003e\n\u003cli\u003eBlack tube cages\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Fezz Audio","offers":[{"title":"Default Title","offer_id":67611374485693,"sku":"1065853","price":14500.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0526\/4175\/9421\/files\/23-Fezz-Audio-Lybra-MK2-Mono-Tube-Power-Amp-Pair-Moonlight-2048x2048.jpg?v=1791212227","url":"https:\/\/moogaudio.com\/products\/fezz-audio-lybra-mk2-mono-tube-power-amp-pair-moonlight","provider":"Moog Audio","version":"1.0","type":"link"}
