All tube amps (especially vintage tube amps) are designed to run at an optimal voltage, and standard 120VAC wall voltage is typically too high for vintage tube amps, as well as some modern designs. With its proprietary 5-amp transformer and flexible attenuation options, the AmpRX BrownBox II lets you bring that voltage down to an optimal level, resulting in significantly improved amp performance.Safe, effective, and easy to use Another benefit of running your amp at optimal voltage is that your tubes will usually last much longer — something many of us here at Sweetwater who’ve paid a pretty penny for new-old-stock tubes can appreciate. The BrownBox II is far safer and\u003c\/p\u003e\u003cp\u003e\u003cb\u003eEAN:\u003c\/b\u003e 0860010348819\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePackage Dimensions:\u003c\/b\u003e 14.0 x 12.0 x 9.0 inches\u003c\/p\u003e","brand":"AmpRX","offers":[{"title":"Default Title","offer_id":54775975837987,"sku":"860010348819_156","price":349.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0566\/1579\/6796\/files\/71HQUkDZqcL.jpg?v=1772141999","url":"https:\/\/almacommerce.com\/products\/amprx-brownbox-ii-tube-amplifier-input-voltage-attenuator","provider":"AllTechRevival","version":"1.0","type":"link"}
