The Genalex Gold Lion PX300B stands out as one of today’s finest 300B audio power triodes. Evoking the classic Western Electric design, it merges traditional craftsmanship with enhanced materials. Its gold-plated grids and contact pins prevent oxide buildup, extending tube life. The unique quadruple spring-loaded filament and cathode supports ensure long-lasting operational stability. With plates longer than typical models, it dissipates 40 watts—6 watts more than Western Electric tubes—delivering fuller bass dynamics before saturation. This tube offers precise midrange clarity and elegant high-frequency detail, making it a top choice for discerning audiophiles.

Matched Sets

Each tube is individually tested, measured, and precisely matched to the same milliamp to ensure consistent electrical performance across every set. This careful matching process promotes balanced operation, reliable response, and long-term stability in your amplifier. Precision milliamp matching is a standard part of our quality control and is included at no additional cost.

Carefully Tested

Every tube is subjected to a comprehensive testing process using custom-designed, calibrated equipment to evaluate key electrical and performance characteristics. Each tube is measured for proper operation, stability, and consistency before it is approved for sale. This thorough testing ensures that only tubes meeting our strict performance standards are shipped, providing dependable operation and long service life.

Burned in

Every tube is subjected to a controlled burn-in process at no additional cost prior to shipment. During burn-in, tubes are operated under load for an extended period to identify early failures and ensure stable, reliable performance. This process helps eliminate weak or unstable tubes before they ever reach your amplifier.
