Always wanted to make one of these. It's a guitar amp using a single valve - the very cooly named compactron 6AF11. It's essentially an amp in a bottle - 2 triodes and a pentode output stage. Uses a groovy 12-pin base.
These are a little tricky to get right, having all the gain stages in one small valve, but I think I've nailed this one. The outcome was a real surprise, breaks up very smoothly and has a really nice crunch. Not much clean headroom to speak of, but plays very nicely with a guitar volume control.
It's not loud - 2w at max, but it sounds (and looks) amazing. I'm particularly pleased with how the ventilation/viewing hole turned
I've built 4 more dinky enclosures the same so I might churn some out.
Pics for your delight...

Looks ace by the way, need to hear some clips.
