Your front end looks very similar to what I had in mind. The cascaded diff amp is a beautiful thing. I've been thinking of higher loads for the 12SN7, more like 56k, but the 5687 is right on at 20 k. Mills WW anybody?
Oh yes, all the diff amps will run cascoded ccs, mmmmhhhhh,cascode ccs.
I already built a similar front end, one with 6SN7> > 6BL7 for my Dyna Mk.iii and 6SN7> > 12B4A in my ground-up monoblocks. very nice front end design.
12SN7> > > 5687 should be O-Tay!!!
