/diy/ - Do It Yourself

I salvaged a bunch of tubes from a wrecked organ that I couldn't just leave alone. Let me crawl out of bed and post a model number. But first, what's a sweet little project I can make from tubes to test that they work? I saw a mini amp kit, but it was like 80 bucks. I already have tubes, so that just seems too expensive. I basically want to make something easy, then sell off the tubes for a fat wad and buy a tube amp maybe. I'd love to wave the wad in front of the assholes that wrecked the organ.
