Ghede, if you have the time, I wouldn't mind getting in line for a little SpaceXpander repair. I really like the enclosure you built for it, too. For mine I'm picturing something in dark hardwood.
I also noticed that in the user's manual, they say to mount the springs
vertically, which I suppose makes sense, but I've yet to see a guitar amp where the springs aren't sitting horizontal.
Hmm.
