Jeff - the PS mentioned is what I'm using for the PP 6B4G. The caps are 50uf motor runs for the B+ sections. One front end I want to try uses negative voltage for a LTP. That section is all SS - a FW bridge using Schottky diodes then CRC to the tail using Panasonic caps. Input tubes will either be 2C22s or a combination of 2C22 and 6SN7. I'll probably try a couple front end ideas but those are the tubes I want to try. The link below covers some of my questions about front end possibilites (if you have the time to read it - it's long). I think you were "on vacation" at the time. That thread was then continued briefly at:

By the way, when you suggest heavy AWG wire, what guage do you call heavy? And which connections, in particular, do you use this for? Everything? I've been using the regular hook up wire I have on hand.
The SE 45 (the "Bugle" design by Gordon Rankin) was built according to his schematic but with scrounged iron. I call it the "Budget Bugle". Power tranny came from a 1930 Philco. Output transformers were made by Stancor and came from a Wards console that ran SE 7868 outputs. So definitely NOT done optimally!
