6AS7GA / 6080 GE NOS NIB Military Green Label – Matched Pair for OTL Amplifiers – Made in USA 1986

Direct 6080 Replacement – AMPLITREX Tested – MOLTO FORTE – Real OTL Matching at 55 mA

Description

Not just a simple "matched" pair: real selection on Amplitrex for OTL use at 55 mA per section, with attention to stability and consistency between tubes.

Matched pair of 6AS7GA / 6080 GE NOS NIB specifically selected for OTL amplifiers, headphone amplifiers, and circuits compatible with the 6AS7 / 6080 family.

This is not just a simple NOS pair matched only by brand or date code: the two tubes have been tested and selected in our laboratory for stability, consistency between sections, and real behavior in Auto Bias at 55 mA per section, a particularly significant condition for OTL applications.

The tubes have been classified as MOLTO FORTE (VERY STRONG), with stable emission, well-balanced sections, consistent behavior between the two tubes, no shorts, gas, or instability.

These are genuine NOS NIB – New Old Stock, New In Box tubes, never used, sourced from DLA – Defense Logistics Agency military stock. General Electric production, Made in USA 1986, Owensboro, Kentucky plant, with military green GE silk screen and original packaging.

The construction features black plates, a robust internal structure, and a domed chrome getter. The manufacturing code 86-48 identifies the 48th week of 1986.

Sonically, they offer a solid, stable, and musical performance, with full and controlled bass, natural mids, sweet highs, and fluid dynamics. The soundstage is wide, orderly, and well-balanced, favored by the electrical consistency of the pair.

Ideal for compatible OTL amplifiers, headphone amplifiers, high-current hi-fi circuits, regulators, power buffers, and equipment designed for 6AS7GA / 6080.

A truly tested and selected military GE NOS pair from Vacuum Tubes Treasures, designed for those seeking authentic, strong, stable American 6AS7GA tubes ready for serious OTL applications.
