This is a well matched pair of RCA 5U4GB tall bottle vacuum tubes. These tubes have a tall glass bottle with RCA markings on the base. They test very strong, with greater than NOS readings. They were manufactured to rigorous industrial specifications for superior quality and long life. They have black plates, faded or white/red lettering, clear glass, and top or side getter. These are excellent RCA 5U4 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 this tube 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.
