Tube monoblock options?

Anyone have a good suggestion for tube monoblocks? I've been holding out for a used pair of MC75-III's, but hard to come by. The system is comprised of Oppo-205, Mcintosh C52 and McIntosh MC275-6.  I don't want to get another 275, since my dealer told me that "just because you can bridge the 275, doesn't mean you should".  Anyone have a comparable option to the mc75? Entire system is balanced, so would like to stay away from SE.
