    Is a KT90 a good tube?
    The KT120 ups the performance level and the survival rate of the KT88 tube run at today's voltages. It sounds like a high performance KT88. The KT90 has a sound somewhere between an EL34 and a KT88 with voltage ratings about equal to a really good KT88. The failure of some examples has been spectacular however.

    Does KT90 & KT88 have a big THD difference?
    Looking at the graph there‘s a large THD difference with the KT90 & KT88 operating at different B+ voltages. It appears that the EI KT90 it isn’t optimised for true UL operation, as the relationship with the O/P tranny falls apart in the midrange; hence the THD staggers upward.

    Is KT90 a good AMP?
    It sounds like a high performance KT88. The KT90 has a sound somewhere between an EL34 and a KT88 with voltage ratings about equal to a really good KT88. The failure of some examples has been spectacular however. I have yet to see a KT120 fail or have a set wear out in any amp that I have had or sold to a customer who has reported such anyway.

    Which KT 88 is better KT 88 or sev 6550c?
    Evem thouth the kt-90 had great bass and a more lively upfront sound it was the least musicsal. The KT-88 has a lush and sweet midrange and high frequencys. The sev 6550c have great base also with more bottom end slam, although it lacks the clarity and sweet midrange of the kt-88. Both are excellent current production tubes.

    Is a KT 88 better than a 90?
    The 90 provides about 15% more output power than a KT 88 (more headroom). It also seems to extend the bass down about an octave. It also sucks out some of the midrange and provides less highs than the 88. There also seems to be increased intermodulation distortion in the 90 but that could be a product of poor matching.

    Should I use a kt-90 or a 6550?
    When using KT-90's instead of KT-88's or 6550's, you need to understand what the bais range of your amp is. I find KT-90's draw the least bias current under the same circut conditions followed by 6550 and then KT-88's. Main issue is that your amp may not have a wide enough bias adjust range to tube the tubes in to the correct bias.

    2016年2月25日 · I actually went KT120 for my Bogen because they were cheaper than KT88 tubes. Jim McShane sells them for $190 a quad. Gold Lion KT88 quads run $225. The KT-90 runs $180 a quad. There really isn't any …
