Input stage ECC83, ECC82, output\u003cbr\u003eEL34 push-pull and Lundal output\u003cbr\u003etransformer with UL connection make\u003cbr\u003e31W+31W output power.\u003cbr\u003eAmplifier uses the 22mm thick solid maple\u003cbr\u003ewood frame and 4mm top solid aluminium\u003cbr\u003eplate, thus the body structure is perfectly\u003cbr\u003erigid and no deflection. The heavyweight\u003cbr\u003etransformer and sensitive vacuum tube\u003cbr\u003eparts are supported by this body to\u003cbr\u003ereproduce the substantial mid-low\u003cbr\u003efrequencies and delicate high frequencies.\u003cbr\u003eThis is designed and manufactured\u003cbr\u003ecarefully hand crafted so that it can not only\u003cbr\u003emeet the needs of the modern digital high resolution era, but also has sufficient\u003cbr\u003efunctions and performance for analog\u003cbr\u003eplayback. This can be used for many years to\u003cbr\u003ecome as The Tube Amplifier that will remain\u003cbr\u003eunchanged for decades to come.\u003c\/p\u003e\n\u003cp\u003eFeature\u003cbr\u003eAs a basic pre-main amplifier, it is equipped\u003cbr\u003ewith 4 RCA line inputs and volume as a\u003cbr\u003estandard model. Three types of option are\u003cbr\u003eavailable, 1: XLR input x1 + RCA x3, 2:MM\u003cbr\u003ephono + 3 RCA, 3: an RCA\/XLR input as a\u003cbr\u003epower amplifier. The backside panel can be\u003cbr\u003ereplaced according to each option, so you can\u003cbr\u003echoose in advance or change it later.\u003cbr\u003eThe resistors parts are Vishay, PRP and\u003cbr\u003eJapanese TAKUMAN, the film capacitors are\u003cbr\u003eWIMA in Germany, and the electrolytic\u003cbr\u003ecapacitors are TDK-EPCOS. We pay attention\u003cbr\u003eabout the quality and reliability of these parts.\u003cbr\u003eThe power transformer and choke\u003cbr\u003etransformer are made in Japan customized\u003cbr\u003efor Aurorasound, the rectifier diode is ROHM\u003cbr\u003esilicon carbide, which is the lowest noise and\u003cbr\u003ehigh voltage capability up to date. Various\u003cbr\u003eterminals are also carefully selected with\u003cbr\u003ethick wall gold plating. The EL34 has a self bias operation system that is easy to\u003cbr\u003emaintenance, so can be replaced to other\u003cbr\u003ebrand EL34h without bias readjustment.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cbr\u003eInput: Standard : RCA LINE x4,\u003cbr\u003eOption 1 : Phono(MM) x1 、RCA LINEx3\u003cbr\u003eOption 2 : XLR\/RCA x1, No volume, no selector SW\u003cbr\u003eGain, Input sensitivity: 31dB, 440ｍV\u003cbr\u003eInput impedance: 25kΩ\u003cbr\u003eOutput: 31W +31W @8ohm\u003cbr\u003eFrequency response: 10Hz – 30kHz, -3dB\u003cbr\u003eTHD+N: 0.1% 1kHz 2\u003cbr\u003eSNR: 98dB A-weighted\u003cbr\u003eAC power voltage: Europe\/Asia model 240V, 230V, USA model 120V, Power consumption 200W\u003cbr\u003eSize, Weight: W440 x D290 xH228mm without knobs\/terminals 、 20kg\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Aurorasound","offers":[{"title":"Standard","offer_id":57087075156341,"sku":null,"price":9699.95,"currency_code":"GBP","in_stock":true},{"title":"with MM phono stage","offer_id":57087075221877,"sku":null,"price":9999.9,"currency_code":"GBP","in_stock":true},{"title":"With remote control","offer_id":57087075254645,"sku":null,"price":9999.9,"currency_code":"GBP","in_stock":true},{"title":"With MM Phono stage and remote control","offer_id":57087075352949,"sku":null,"price":10299.85,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2222\/0805\/files\/ABnqaa-2H-6DpMYPnNzH-AI_0_gps_generated_4a673297-06da-41b4-afc8-7cede0a906dc.png?v=1776949525","url":"https:\/\/www.kronosav.com\/products\/ygyu","provider":"Kronos AV","version":"1.0","type":"link"}
