Hey Mike,I was scribbling away at PP811A ideas, inspired by Jim Doyle's (?) post a while back, trying to shoehorn the whole thing into a 3-stage direct coupled compact (6SN7-6A5Gcf-811A), and then I come across this link at Ned's site. Well, well. Look at that "17173" sitting in the driver cathode circuit (and there's also a 15095 on the page). The EXO-173 can't take any DC current right? So its a parafeed version of the 17173? The fifties were good for audio, I take it?
