National Union 6V6GT Black Glass Well Matched (2.3%) Pair NOS 6V6

This is a well matched pair of National Union 6V6GT vacuum tubes. The tubes were made in the USA and have the National Union label on each tube, and one is branded Sonora snd the other is branded Motorola.  These tubes are visually closely matched.  Both tubes test closely to each other. They were manufactured to rigorous industrial specifications so you can expect low noise and microphonics. They have black glass, white or yellow lettering, and bottom getters. These are excellent National Union 6V6GT tubes that are highly sought after, act quickly before these sell out! More available upon request.

Be careful buying tubes from sellers who list tubes as matched if they do not provide test results or the equipment that they tested their tubes on.

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

4,250
4,150
