Il suo livello di guadagno più contenuto rispetto ad altri modelli molto diffusi la rende una scelta apprezzata per ritrovare comportamenti \"old school\": dinamica, definizione e una salita in saturazione meno brusca quando si spinge il preamplificatore.\u003c\/p\u003e\u003ch3\u003ePer chi e per quali usi?\u003c\/h3\u003e\u003cp\u003eQuesta valvola è rivolta ai chitarristi che vogliono \u003cstrong\u003ecalmare un canale troppo nervoso\u003c\/strong\u003e, guadagnare chiarezza negli attacchi o ampliare la gamma di utilizzo prima della distorsione. È adatta anche agli utilizzatori di preamplificatori\/stadi a valvole che cercano una resa musicale, con un guadagno controllato e una risposta più morbida alle sfumature del tocco.\u003c\/p\u003e\u003ch3\u003eUn carattere di guadagno moderato, al servizio della dinamica\u003c\/h3\u003e\u003cp\u003eIn pratica, la 12AY7 è spesso scelta per bilanciare un preamplificatore: meno compressione immediata, maggiore margine prima della saturazione e una sensazione di controllo aumentata sul volume della chitarra. Il risultato dipende dal circuito (polarizzazione, alimentazione, trasformatori), ma la 12AY7 rimane un'opzione pertinente per affinare il tocco e la progressività.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifiche tecniche\u003c\/h2\u003e\n\u003cstyle\u003e@media(max-width:632px){table[data-wb-spec]{display:grid;grid-template-columns:minmax(0,1fr) minmax(0,1fr)}table[data-wb-spec] colgroup{display:none}table[data-wb-spec] tbody,table[data-wb-spec] tr{display:contents}table[data-wb-spec] td{display:block;overflow-wrap:anywhere;grid-row:var(--wb-l);background-color:var(--wb-lb)}table[data-wb-spec] td[data-r]{grid-row:var(--wb-r);background-color:var(--wb-rb)}table[data-wb-spec] td[colspan=\"2\"]{grid-column:1\/-1}table[data-wb-spec] td:empty{display:none}}\u003c\/style\u003e\n\u003ctable data-wb-spec style=\"width:100%;table-layout:fixed\"\u003e\n\u003ccolgroup\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003c\/colgroup\u003e\n  \u003ctr style=\"background-color:var(--wb-neutral-50);--wb-l:1;--wb-r:3;--wb-lb:var(--wb-neutral-50);--wb-rb:var(--wb-neutral-50)\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eCategoria\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003elampada\u003c\/td\u003e\u003ctd data-r style=\"text-align:left\"\u003e\u003cstrong\u003eDenominazione\u003c\/strong\u003e\u003c\/td\u003e\u003ctd data-r style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003eacc8_denomination_12ay7_6072\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr style=\"background-color:transparent;--wb-l:2;--wb-r:4;--wb-lb:transparent;--wb-rb:transparent\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eAssegnazione\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003ePreamplificatore, ampli, Stadio preamplificatore\u003c\/td\u003e\u003ctd data-r style=\"text-align:left\"\u003e\u003cstrong\u003eQuantità\u003c\/strong\u003e\u003c\/td\u003e\u003ctd data-r style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e1\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ctable data-wb-spec style=\"width:100%;table-layout:fixed\"\u003e\n\u003ccolgroup\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003c\/colgroup\u003e\n  \u003ctr style=\"background-color:var(--wb-neutral-50);--wb-l:1;--wb-r:4;--wb-lb:var(--wb-neutral-50);--wb-rb:transparent\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eTipo\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003evalvola di preamplificazione\u003c\/td\u003e\u003ctd data-r style=\"text-align:left\"\u003e\u003cstrong\u003ePinout\u003c\/strong\u003e\u003c\/td\u003e\u003ctd data-r style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e9 pin\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr style=\"background-color:transparent;--wb-l:2;--wb-r:5;--wb-lb:transparent;--wb-rb:var(--wb-neutral-50)\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eTecnologia\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003edoppia triode\u003c\/td\u003e\u003ctd data-r style=\"text-align:left\"\u003e\u003cstrong\u003eTensione di riscaldamento\u003c\/strong\u003e\u003c\/td\u003e\u003ctd data-r style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e6,3 V o 12,6 V (a seconda del cablaggio)\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr style=\"background-color:var(--wb-neutral-50);--wb-l:3;--wb-r:6;--wb-lb:var(--wb-neutral-50);--wb-rb:transparent\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eSupporto\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003eNoval\u003c\/td\u003e\u003ctd data-r style=\"text-align:left\"\u003e\u003cstrong\u003eEquivalenze comuni\u003c\/strong\u003e\u003c\/td\u003e\u003ctd data-r style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e6072 \/ 6072A\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"JJ","offers":[{"title":"Default Title","offer_id":54361416761619,"sku":"364583","price":46.0,"currency_code":"CHF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/0872\/6803\/files\/9170c7e867cd7356d85beb5ad2d05926a6a42e46_FILLING_JJ12AY7.jpg?v=1792639349","url":"https:\/\/woodbrass.ch\/it\/products\/jj-12ay7-364583","provider":"Woodbrass.com","version":"1.0","type":"link"}
