This is a matched pair of Tung-Sol 6X4 vacuum tubes. These tubes have a 7 pin tall glass bottle, and they were made in the USA by Tung-Sol for FoMoCo. They test very strong, with greater than NOS readings. They are visually very similar to each other. These tubes have black plates, clear glass, white or faded lettering, and top angled square getters. This is an excellent pair of Tung-Sol 6X4 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:
Pass/Pass
Pass/Pass
*Rectifiers test on a pass fail scale, they are not measured on gm or transconductance.
