We're into finding and keeping old vintage audio equipment such as tube amplifiers, field coil speakers, and anything art-deco-esque. But we were in need of a guitar amplifier, so when we came across a gutted 1936 Philco Tombstone radio case, we knew we had a project!

This series of videos shows how we combined a 1936 Philco Tombstone radio case with a 1940s field coil speaker from an old Hammond organ and 1960s Leslie Type 25 tube amplifier complete with a DIY power supply capable of providing 115VAC, 8-10 VDC, and 90VDC for the different components!

A full write-up will be in AudioXpress's September 2014 edition!

    Didn't notice that it's actually a playlist till the first part ended, but unfortunatly I don't have time to watch it all :(, so I skipped to the end. The sound isn't that impressive, but I may (and I'm pretty sure it does) sound better live. However it realy is a true unique piece of art. Thumbs up!

    We're still tweaking the sound a bit and have plans to exchange the current preamp for a DIY tube preamp, which should help the sound out a bit. We have some other samples of how else it can sound: https://www.youtube.com/watch?v=66MyP0dzqCc
