Do we still need 6550 or KT88 tubes?

Mikha65, thanks, I'm glad to hear there's another option for the VT100. I had been told the 120 would not work because of the horizontal orientation of the tubes.

The KT-120 is my second favorite tube in my Emotive Vita amps. My very favorite is the Genalex KT-77. No reliability problems with either type.

I think Atmasphere was more than a little unfair in repeating gossip about the KT-120 having reliability problems. Sure, there will always be the occasional defective tube and the unfortunate owner may vent his frustration. That's understandable. But after several years I haven't heard of any problems with the KT-120. By now word would have gotten out if this were true.

I think Wolf Garcia said something like that earlier.

I have tried kt 120, WC 6550, GL kt88, JJ kt88, Ei kt90, sovtek kt88, I luked the 6550 WC best, just more musically convincing. In other systems this was not the case. The plate impedance is diffwrent for each tube so they are very system dependant. Try first in your system...Jallen
