​Elevate your restoration project with this curated lot of five 01A (201A) vacuum tubes, featuring the sought-after "Silver Tone" finish. These tubes aren't just functional components; they are the aesthetic and performance cornerstone for any serious 1920s battery radio restoration or custom triode audio build.

​Why This Lot Stands Out:

​Distinctive Aesthetic: The unique "Silver Tone" finish provides a striking, high-end look that stands out in open-chassis builds or glass-enclosed display cases.

​The Classic 01A Experience: Renowned for the warm, rich, and harmonic-heavy sound characteristic of early thoriated tungsten triodes.

​Tested & Reliable: Each of the five tubes in this lot has undergone rigorous filament and emission testing to ensure they are ready for immediate use in your receiver or amplifier.

​Broad Compatibility: Fully compatible with standard 4-pin (UX-4) sockets and interchangeable with 201A, 301A, and CX201A designations.

​Specifications:

​Quantity: 5 Tubes

​Type: 01A (201A) Triode

​Finish: Silver Tone

​Base: 4-Pin (UX-4)

​Condition: Vintage, tested for emission and filament continuity.

​Collector’s Note: These Silver Tone variants are a favorite among enthusiasts who value both the technical performance of the 01A and the visual elegance of the silver-finished envelope. As with all century-old components, please ensure your circuit is properly aligned before powering up to maintain the health of these rare tubes
