    Hi!

    I have a pair of WE 300B tubes that I need to test. My tester (and those I have access to) doesn't have a 4-pin slot for such things.

    Is there anyone in the California Bay Area that might help me out? Preferably a Mutual Conductance tester? Any ideas where to look?

    THANK YOU.

    I have a Hickok 600A, which ought to do the trick, and am located in San Francisco. I'd be happy to help you test these tubes, but my schedule precludes being able to meet up until the weekend right before Christmas.

    That's great to know! I'm in the city, too.

    If I don't find assistance before then, I'll certainly be in touch. Thanks!

    I have a calibrated TV-7A/U tester up in Sebastopol.

    Did you calibrate the tester yourself?
