Lew, the only reason I've stuck to lower mu is tube matching (plus of course that is all that is practically available...). Of course mu is not the whole story by any means, but if you have a higher mu (voltage gain in essence) then you will have to be more careful about matching power tubes. Beyond that I see no reason not to try it- in your amps and in the later Novacrons they are equipped with an independent driver and bias control for each power tube, so at least you can set the base bias point correctly. Its still a good idea to match when you are dealing with such high transconductance as these tubes have! (the exclamation point is a bit of an understatement, BTW...)
