Do any Audio Research tube amps run in class A?

I have an ARC VT100 mk II, which is a class AB amp. I am thinking ahead on my upgrade path, and I am toying with the idea of a pair of class A tube mono blocks.  As I began my research, I found it challenging to know the class of operation on the various audio research power amps. Does anyone know which of the audio research power amps run in class A (stereo or mono)?

Hello,
To the best of my knowledge I believe that all ARC tube power amplifiers have always been class A/B  designs.

 I also believe that all Audio Research tube amps are A/B. It would increase the number of tubes significantly to be class A at the same power output. I went from a VT100 mk3 to a Ref 110 and it was a big jump. I always felt that my VT100 lacked presence. I also had a V70 at the time. The VT100 was more detailed with a bigger sound stage. But the V70 had a way of making you feel the singer was in the room. The Ref 110 has the best qualities of both. Eventually I will upgrade to a Ref 150se but right now I am truly happy with my Ref 110.
