Cardio, you might want to check in to Getchell Amplifiers for that amp... Bobby is a genius with amp electronics and could probably figure it out fairly easily. He's done some great work on a few of my amps and I got one of his little 1x8 custom builds that sings - he used to work out of the back of Dave's place but now he's got his own shop in Brownsburg. I know it's not the most convenient since you're out west but you could probably just pack it up the next time you head to the Burg and stop by his shop. It's right off of 267 close to Marsh...
I'm thinking that if they're simple enough that you think you can build them, then they should be simple enough for you trace out. You could post it here or over at DIYSB and have some folks double check for you. The worst part is probably going to be reading the component values. I hate resistor colors!
If you've got the software, you could take reasonable photos of both sides of the board and then mirror the trace side, make it semi-transparent, and lay it over the component side. Might make it easier to sort out.
Be very careful with that amp, though. The output power is small, but the input power is still the wall and can fuck up your day pretty quick. Unless you really know what you're doing around high voltage and know the proper safety procedures without having to ask on a web forum, you should probably outsource that one to a pro.
He does make some pretty badass amps; I've got one he built into an old Crate combo cabinet that he named the blues king. It's a little 1 x 8" all hardwired (no PCB) 5 watt beast that fills a niche void in my collection. It gets played often... But, I digress...I've looked at his amps and thought they were cool designs (like the ammo box) and Dave said they were great, but I never actually played one or heard anybody there who was playing one. And I could never justify spending that kind of money on an amp unless it was a blackface Deluxe Reverb or maybe a Princeton. I did come close to buying Travis' head once, but I just couldn't come up with the money in time.
I didn't realize he worked on amps though, other than his own.
