    Oh?
    I'll send you a few culls, if you want!
    Least I could do. ;)

    PS They'll be good culls, not just cannon fodder. I'll check 'em quantitatively & qualitatively! :)

    I don't know who I've sent what to -- fortunately, so far (!?) I've managed not to buy back too many things that I donated to charity auctions and fleamarkets. :blush:

    Nice collection! Are you using those or just hanging onto them?

    I just have these hanging around here. I am willing to part with a few. I would have to see what I paid for them. I will never use all of these. I found the popes that I wanted so these are part of my collection of tubes. I know I didn't loose any money buying these a few years ago.

    Not a direct substitute for a 6SN7, though.
    And the filament current supply might be tricky to implement.
    B)

    EDIT: On the other hand, it (probably) is a triode. Probably low mu, though.

    That's what I get for shootin' from the hip. :p
    Yup, it does indeed.
    Thyratron -- useful for thermonuclear bombs, radar, and remote controls, not so much in hifi.
    They are kinda triode-y, though. B)

    Not all tubes are magic, though.
    1B3 HV rectifiers, e.g., from the days of B&W TV.
    Not magic.

    The problem with nos tubes is they could actually have more time on them than you think even though they might measure nos. They really knew how to make a long lasting tube back then.
