RCA Black Plate 6SN7GT Well Matched Pair (2.5%) NOS 6SN7

This is a well matched pair of RCA 6SN7GT vacuum tubes. Both tubes test very close to each other. Both tubes have RCA factory style micas and plates. They both have a medium, clear glass envelope and a black base. They were manufactured to rigorous industrial standards, so you can expect low noise and mirophonics. They both have staggered black plates, bottom getters, and silver or faded lettering. These are highly sought after RCA 6SN7GT tubes, act quickly before they 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:

3,000/2,950
3,000/2,925
