Battery Valve Guitar Amplifier

Self isolating can be boring so I've been building and fixing things. My latest project is a guitar amplifier made from battery valves as used in 1940's and 50's portable radios. It delivers a bit over a quarter of a watt but is surprisingly loud. It goes from clean to crunchy to a Tweed-like overdrive. For something I whipped up and designed myself, I'm very surprised and pleased with how it turned out.

Although it could easily run with batteries without any issues, I didn't have any on hand so I used a nice old bench power supply as a substitute.

Jump to around 11:00 to skip my constant yammering and hear the damn thing. If you like it, you can build one yourself. The schematic is here - https://www.flickr.com/photos/35799859@N00/49869143441
