Somewhat belated, but here’s a small video of our first amp build, the little blue amp, a small 5 watt tube based amp for home/rehearsal use:

The content isn’t great, as I was a bit rushed that day trying to do too many things, but hopefully gives you a good idea of how the amp works :) My thanks to Tristan for salvaging something from the mound of video I recorded; next time I’ll get him to film the lot :)
