    7199 or 6gh8

    Post by ulath on Sat Apr 14, 2018 1:31 pm

    Anyone can help me with the choice between 7199 or 6gh8 tube? I was reading that 7199 has less capacitance between the grids, then would be better... Actually they are almost the same with different pinout (I already have the adaptors) but yet i am not sure which is better... less THD,... etc
    Thanks for your help!

    I ditched them both years ago and installed the Tubes4HiFi board. Big improvement. No regrets. This was in an ST70 where I first installed the old Sound Valves board. Used that for well over 10 years and then went with the Tubes4hifi board.

    7199 is scarce and expensive. They won't be easier to get and the ones that is available
    is in many cases rejects from some earlier vendor.
    6GH8 or even better 6U8 is also not in production but has many more tubes "out there" at
    a more reasonable price.
