 My test mule/breadboard is just about complete. Center front is the adjustable B+ supply. A variac will adjust the B+ from 0 to probably about 450 vdc. Center back is the filament voltages unit. 5 vac and 6.3 vac at the moment, each with it's own on/off switch and fuse, and the whole unit has a separate ac supply. On each side is a "front end" for tubes etc. Might work on those more later, but I want to give it a try first. I have a SE and PP output tranny for each side as well. Going to the Dayton hamfest on Thursday, so I will wait until I get back to try it out. This one should be a lot easier and more fun to use than my old method of clip leads, not to mention a bit safer.
