This is matched pair of Sylvania 6U8A vacuum tubes. These tubes have a 9 pin medium glass bottle with Sylvania markings on the tubes. Both test very strong, with greater than NOS readings. These tubes were manufactured to rigorous industrial specifications and you can expect low noise and great performance. These tubes test closely to each other. These tubes are visually almost identical. Each tube has gray plates, yellow lettering, and a top halo getter. These are excellent Sylvania 6U8A 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 pairs" 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:
130/94
125/88
