This is a well matched pair of RCA JAN CRC 6SN7GT vacuum tubes. They were manufactured in the USA by RCA for the US military. They have a medium glass envelope and a thick, black base. Both tubes test very close to each other. They were manufactured to rigorous military specifications, so you can expect low noise and microphonics. These tubes have staggered black plates, white lettering, and a bottom getter. These are highly sought after RCA JAN 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:
2,575/2,550
2,650/2,475
