RCA 6X5GT Gray Plate Well Matched Pair NOS Rectifier 6X5

This is a well matched pair of RCA 6X5GT vacuum tubes. The tubes have a medium glass bottle and both have RCA markings on each tube.  These tubes are visually very closely matched. They test very close to each other, and stronger than NOS They have gray plates, clear glass, red lettering, and bottom getters. These are excellent RCA 6X5 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
