GE JAN JLRV 6189 Gray Plate Well Matched Pair (3.7%) NOS 12AU7 6189W ECC82

This is a pair of GE JAN 6189 tubes. These tubes were manufactured in Canada. They test very close to each other, and stronger than NOS. These tubes have been manufactured to meet the highest military standards. Both of these tubes have 14mm gray plates, matching date codes, and red lettering. These are excellent GE 6189/12AU7 tubes that are highly sought after, act quickly before they sell out!! More available upon request.

Be careful buying tubes from other sellers who list "matched pairs" but do not provide test results or specify the equipment that they use to test their tubes.

I personally tested these tubes on my recently calibrated Hickok 600a and my TV7D/U tube testers and the results are as follows:

2,575/2,650
2,625/2,550
