Name the tube amp in the Lexus commercial


I just saw a Lexus commercial tonight that featured a tube amp and the commentary "...this produces frequencies that only a dog can hear.." Can anyone identify the amp in the ad?

I think there are two versions of the commercial. One where he talks about how rare it is, one where he says only dogs can hear it.
