Key Features and Technology
- Black HPCC Coating: Features a high polymer compound carbon glass coating designed to minimize internal photon/electron interference and lower background noise. [1, 2]
- Super Alloy Construction: Utilizes aerospace-grade super alloy materials for single-crystal molecular structures to enhance electron emission and current stability. [1, 2]
- Hand-Assembled: Built and matched by senior technicians with over 30 years of experience through more than 100 individual assembly and testing steps. [1, 2]
- Burn-In Period: Typically requires around 150 to 300 hours of burn-in time to stabilize and reach optimal sonic performance. [1]
Pricing and Availability
- Market Price: A factory-matched pair typically ranges from about $250 to $440 USD (approximately £170–£395/pr depending on the retailer, region, and whether they are sourced via eBay, AliExpress, or specialty audio distributors). [1, 2, 3]
- Compatibility: Designed as a direct drop-in replacement for standard 300B triodes used in single-ended triode (SET) or push-pull tube amplifiers (such as Psvane, Western Electric, Electro-Harmonix, and JJ variants). [1, 2, 3]
