Portable tube amp

By Ben Everard. Posted

This beautiful build is a portable push-pull tube amp. In the tradition of audio equipment, this won’t work on its own – you need a speaker cabinet to plug it into, plus a guitar, and maybe even enough talent to be able to play the thing.

What makes it stand out is the sheer amount of electronics packed into such a small space. It’s built into a Hammond 125B enclosure measuring around 120 × 65 × 40 mm; that enclosure is also typically used in guitar effects pedals, so packing a whole amplifier in – and one that uses three full-sized vacuum tubes – is seriously impressive.
