Offered here is a rare set of four (4) genuine New Old Stock (NOS) Sylvania 6SL7GT vacuum tubes, still housed in their original JAN (Joint Army-Navy) military-spec packaging.

​These are not just standard tubes; these are high-grade military production units built for maximum durability and performance. Perfect for audiophiles restoring vintage high-fidelity amplifiers, preamps, or high-end guitar gear that demands the best-in-class NOS components.

​Brand: Sylvania (Military Production)

​Status: New Old Stock (Never used)

​Packaging: Original JAN-labeled military boxes included

​Condition: Exceptional. Glass is pristine, pins are clean/bright, and getters are full and mirror-like.

​Why these matter:

JAN-specification tubes are held to stricter tolerances than standard commercial tubes. Having the original matching boxes significantly increases their provenance and value for serious collectors and audio enthusiasts who demand period-correct, authentic military-grade components
