Thread: Sophia (blue) EL-34-ST Tubes

  1. #11
    Wondering if anyone has compared these to the true NOS like XF2's or Sylvania Fat Bottle?

    I listed the tubes I have 2 posts back, which include some NOS varieties. The old Teslas (pre-JJ) are probably the closest to the Sophias, but the Sophias really have a different character vs any other EL34 type I've tried.

    I'm switching back to the GL KT77 today, should be interesting... I've been thinking the Sophias are maybe a bit too much as far as midrange bloom/warmth for my system, we will see!
