What amps use the KT120 tubes?

As per the title -- can anyone list amps that use these tubes by design (not retrofit )?
Just adding this list to help out anyone who may stumble upon this thread.

The following is a list of ARC amps that are authorized to use the KT-120:

VS55, VSi55, VS60, VSi60, VS110, VS115, REF110, VM220. I hope people find this useful as there seems to be a lot of confusion about it.
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.
