I already have a set of Handmade iron exactly as you describe that I bought years ago for my old ST 70; as well as most of the rest of the parts. Lead the way I would be interested in participating with whomever chooses to build. Will you stay with it if possible and where is the schematic? BTW; I have begun dismantling the Guinevere with the intention of rebuilding into the new chassis. I have decided this is the pre-amp for me. I have heard nothing better. Right now I'm searching for a better volume pot and some better quality connectors and RCA's.
