This is a well matched pair of RCA 6SN7GTB vacuum tubes. They were manufactured in the USA by RCA. They have a short glass envelope and a slim, black base. Both tubes test very close to each other. They were manufactured to rigorous industrial specifications, so you can expect low noise and microphonics. These tubes have staggered black plates, red or white lettering, and a single side getter. These are highly sought after RCA 6SN7GTB 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:
2,325/2,450
2,350/2,400
