As the first and only preamplifier to use the legendary directly heated 300B triode as a line driver, this all-triode design pairs the 300B with a classic 6SL7GT input stage, running entirely in pure Class A operation for a smooth, natural, organic sound with exceptional dimensional imaging. It doubles as a genuinely capable headphone amplifier, with a dedicated Class A 300B output stage and a three-position impedance selector that properly matches headphones from 30 to 4,000 ohms — a rarity among preamplifiers. Vacuum tube rectification, regulation, and an innovative ripple rejection circuit combine for an unusually quiet noise floor, letting fine micro-dynamic detail come through clearly. A wireless RF remote controls a precision motorized ALPS volume pot for smooth, convenient operation. Hand-built in California, the Neo-Classic 300B remains a cult favorite for its warm, detailed, and remarkably transparent tube sound. Shows excellent condition with no notable wear.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eWe do take trade-ins, so please contact us if you wish to do so.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease make sure to thoroughly inspect item photos for cosmetic condition.  We do try to describe the item as accurately as possible, so if you have any questions about cosmetic condition please message us.\u003c\/strong\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Manley Laboratories","offers":[{"title":"Default Title","offer_id":46167901470780,"sku":null,"price":4995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0610\/9573\/9452\/files\/IMG_1702.jpg?v=1789601087","url":"https:\/\/3maaudio.com\/products\/manley-neo-classic-300b-preamplifier-w-box-excellent","provider":"3mA High End Audio","version":"1.0","type":"link"}
