Pair WESTERN ELECTRIC JAN-CW-337A small punch type Both measure >100% of reference value (=65%) in Hickok TV-7 B/U tester, hence matched pair for stereo! The 337A is the lower-mu proxy of 310A, otherwise both are the same. Play-tested in WE 91A replica SET, the sound WONDERFUL! Perfect driver tube for WE 300A/B. Firm sockets, no rattles, no lose glass inside et al. Getters look great, almost the same (see pic). You only buy what you see in pics. Ship worldwide. Disclaimer: EVERY tube tester (namely Hickok TV-7) might test different from mine, there is NO guarantee that you get exactly the same test results. If you disagree, DO NOT BID!
