    Those hungry filaments....most power transformers don't like them.

    Those PTs are quite replacable. ;)

    I wish nos were more available.
    The valve arts are too mushy for me.

    We've been using the Sovtek/Tung Sol "reissue" in our 45-50 watters with success. I think they're better sounding than their chinese counterparts, and not nearly as spendy as NOS.

    The Sovtek ones are just 6L6GC in a KT66 bottle. Might look like a KT66 and work anywhere a KT66 will...but not a KT66

    Everyone says that but they sound different
    I sat there with tungsol 6l6 and the kt66 and they bias differently and sound bigger.

    Nice tube. Weather or not it's accurate is another argument entirely

    A real KT66 will give you more mids because it's a "kinkless tetrode" which is what the "KT" stands for. My take is that they are more like a 6V6 in sound, but with more power in that way. Having that mid hump that's less scooped.

    I bought a pair of those Sovtek KT66s. After I saw that they were just 6L6 I installed them in a 6L6 amp that couldn't handle the increased filament demand anyway. I really couldn't hear much differemce between those and the Sovtek 6L6GC that were in there. Looking at them side by side it was the exact same guts... just in a different bottle.

    Well they sounded different to me in the same amp.
    I'm talking tungsol branded
