What amps use the KT120 tubes?


As per the title -- can anyone list amps that use these tubes by design (not retrofit )?

Dhcod, do you find that the amp produces a hum through the speakers when paired with the kt120s? I just put these tubes in my titan atlas magnum and there is a hum through the speakers even with nothing else plugged in. I didn't notice it with the 90s.
Emotive Audio Vitas use KT-120s. They can also run 6550, EL34, 6L6GC and their KT counterparts. I like the KT-120s best of all the tubes I've tried so far.
