While I have spent quite a bit of time working on cars, I have worked on all kinds of projects. When I wanted an amp that would get that vintage tone, I considered buying one. There are a number on the market that are nice, hand made examples. For the money though, building one seemed like the better value as well as a lot more fun. So I did a little research and found the Tweed Royal kit at BYOC. It basically comes with bags of parts that you assemble like a giant kit. For someone with some time, patience and some skill with a soldering iron, it is complete with great instructions. So good in fact, mine worked on the first try.
