Type: 2x Sylvania 5814WA (Premium 12AU7 variants)

Purchase Options: Price for one pair of tubes.

Physical Features: Rare black plates, triple mica, D-getter.

Condition: New Old Stock (NOS). These were sourced from a vintage CBC technician’s inventory and have probably never been used

Testing: All tubes have been tested for plate current on a custom-built tester. The tester can supply a set of high voltages and adjust bias, measures plate/grid voltage and plate current. Tubes are matching within 10% range. See test results on the tube boxes

Packaging: Tubes will be safely packed in white generic boxes as the original Sylvania boxes were not preserved


About the Seller: I am a professional network engineer with a passion for classic tone and vintage electronics. I spend my spare time bringing old tube radios back to life, repairing tube guitar amps, and building custom boutique amplifiers. The tubes available in my shop are high-quality spares from my personal inventory. Whether you are retubing a vintage amp or working on a custom project, these components are handled with care and packed securely. Feel free to shoot me a message if you have any technical questions about the tubes listed!
