No I hav'nt but thats because I've heard people don't have much luck with it and it would seem to be as there are no schems floating about. However, I'm at the point where I should make an attempt. I will post my results for humor sake.
From what I remember, the layout of B52's solid state amps looked very similiar to Marshalls early Valvestate amps.
Compare them and see if that's where they got their design.
