Okay it's done and burned in, and is sounds fantastic. This is a homebrew that steals a lot from Dave Hunter's Two Stroke amp. I made a few changes and am digging it. It's basically a Champ format, but in reality it's closer to a tweed Princeton except it has a single power tube instead of two.
I burned in the amp and all voltages were good, so I installed it into a head cab I made for it. That badge on there is a fender emblem from a 1967 Ford Mustang. I have a bunch of metal car badges I've collected over the years, and this one seemed the most appropriate because the amp is based on the Fender Champ.
The control panel is fuse, power switch, lamp, tone, volume, boost/bright switch, and input jack. The Two Stroke circuit employs a three-way selector switch to vary the bias of V1 to give 'normal' Champ tone in the middle position, with up being a treble boost and down being a 'fat' (more mids) boost. It is a very cool feature. I added a switchable negative feedback and a few other small tweaks.
