Questo comporta una maggiore attenzione alla qualità del suono e un'attenzione particolare alla linearità e all'affidabilità della valvola. Il suono potrebbe essere descritto come ricco, caldo e dettagliato, con una buona risposta musicale.  E' caratterizzato da una risposta dei bassi ben controllata, medi ricchi di dettagli e alti nitidi. Le armoniche sono piacevoli e il suono può avere una piacevole morbidezza o rotondità.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eLow Noise \u0026amp; Microphonics\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eStesso Codice di fabbricazione: ANJ 312 052\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eLoghi usurati come da foto.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eTestate su AMPLITREX AT-1000 Tube tester:\u003cbr\u003e\u003c\/strong\u003eMedia 100% Gm = 2200 ; Ia = 10,5 mA\u003cbr\u003eVoltage Test: Va = 250V, Vg = -8,5V\u003cstrong\u003e\u003cbr\u003eRISULTATO DEL TEST: MOLTO FORTE\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eValvola 1:\u003cbr\u003eSezione 1: \u003cmeta charset=\"utf-8\"\u003eGm = 2200 ; Ia = 9,2 mA\u003cbr\u003eSezione 2: \u003cmeta charset=\"utf-8\"\u003eGm = 2200 ; Ia = \u003cmeta charset=\"utf-8\"\u003e9,4 mA\u003cbr\u003eValvola 2:\u003cbr\u003e\u003cmeta charset=\"utf-8\"\u003eSezione 1: \u003cmeta charset=\"utf-8\"\u003eGm = 2150 ; Ia = 9,0 mA\u003cbr\u003eSezione 2: \u003cmeta charset=\"utf-8\"\u003eGm = 2200 ; Ia = 9,2 mA\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e\u003cmeta charset=\"utf-8\"\u003eValvola 3:\u003cbr\u003eSezione 1: \u003cmeta charset=\"utf-8\"\u003eGm = \u003cmeta charset=\"utf-8\"\u003e2150 ; Ia = 8,8 mA\u003cbr\u003eSezione 2: \u003cmeta charset=\"utf-8\"\u003eGm = \u003cmeta charset=\"utf-8\"\u003e2150 ; Ia = 9,2 mA\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e\u003cmeta charset=\"utf-8\"\u003eValvola 4:\u003cbr\u003eSezione 1: \u003cmeta charset=\"utf-8\"\u003eGm = \u003cmeta charset=\"utf-8\"\u003e2200 ; Ia = 9,2 mA\u003cbr\u003eSezione 2: \u003cmeta charset=\"utf-8\"\u003eGm = \u003cmeta charset=\"utf-8\"\u003e2200 ; Ia = 9,4 mA\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eAltri Test effettuati:\u003cbr\u003eTest Microfonia\u003cbr\u003eQualità dell'Emissione\u003cbr\u003eTest per Cortocircuiti\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eTest per GAS\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cmeta charset=\"utf-8\"\u003e \u003ca href=\"https:\/\/vacuumtubestreasures.com\/blogs\/notizie\/perche-le-nostre-valvole-sono-diverse\" title=\"Perché le nostre valvole sono diverse – il protocollo VTT che migliora suono, affidabilità e durata\" rel=\"noopener\" target=\"_blank\"\u003e\u003cstrong\u003eScopra perché le nostre valvole sono diverse →\u003c\/strong\u003e\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"SYLVANIA","offers":[{"title":"Default Title","offer_id":49393743397212,"sku":"02425M","price":638.0,"currency_code":"CNY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0616\/3775\/5127\/files\/1_72bae0b2-3d33-4b1b-ac2c-0be5bd822497.jpg?v=1726764267","url":"https:\/\/vacuumtubestreasures.com\/it-cn\/products\/12au7a-ecc82-nos-sylvania-for-baldwin-long-gray-plates-o-getter-matched-tubes-made-in-usa-50s-copy-copy","provider":"Vacuum Tubes Treasures","version":"1.0","type":"link"}
