This is a well matched pair of Tung-Sol 6SN7GTB vacuum tubes. Both tubes test very close to each other, and they are visually almost identical. Both tubes have the Tung-Sol factory code 322 printed on each tube, and one tube is branded RCA. They both have angled black T plates, top getters, and white lettering. They both have a medium, clear glass envelope and a slim, black base. These are highly sought after Tung-Sol 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:
2,800/2,950
2,975/2,950
