I spoke to K(C?)alvin the other day w/ regard to my CD3 and I asked about the KT120 for my VT200MKI. He said that first the KT120s are in short supply and they are using all they have for their current production. He did say however, that they are planning to determine which previous amps will allow the KT120 to fit and can be properly biased. He seemed to imply that the "modern" amps would not have bias issues if there is room for the tubes. He also stated there was a roughly 20% increase in power over the 6550. They are working on a new website but his advice was to be patient. If the KT120 will work in my VT200 I'll just suck it up and send it back to ARC and let them get it right.
