The Genalex Gold Lion PX300B is one of the best 300B audio power triodes being made today. Reminiscent of the Western Electric tubes of decades ago, the Genalex Gold Lion PX300B combines traditional construction styling with upgraded materials. Gold plated grids and contact pins minimize oxidation to maximize tube life. The unique quadruple spring loaded filament / cathode supports provide consistent stability for years of hard service. The Genalex Gold Lion PX300B tube have a detailed midrange, airy, refined highs.
Factory matched, but we take that a step further and check them again on our own custom-built test equipment. You can expect only the best from Upscale Audio!
