Amperex 6AQ8 ECC85 Vacuum Tube Valve NOS-Testing 6JV8 Milspec new in box US-made 1LN5

new in box US-made 1LN5 tubes tested to spec on our Paul Hart-calibrated TV7/U

but followed the original score and was recorded in the latter 1950s

Transconductance measured 57 for Tube One and 65 for Tube Two where minimum (65%) is 36 and 100% is 55

BUT THAT DEPENDS ON THE LUCK OF THE DRAW

FOUR-STAR REVIEWS OR HAVE LOST A CUSTOMER BECAUSE I REFUSED TO EITHER ISSUE A REFUND FOR A TUBE THAT WENT BAD AFTER IT HAD BEEN USED OR A BUYER KNEW NOTHING ABOUT TUBE REBRANDING AND CLAIMED THAT SOMETHING MADE BY TUNG-SOL AND BRANDED BY EMERSON WAS MADE BY EMERSON
