As a nice counterpoint to the Yamaha portable speaker we showed you yesterday, Los-Angeles-based electrician and artist Devin Ward takes old tube-amp radios, refurbishes them, and wires in a minijack connection so you can plug in your iDevice. The nostalgia might come at a cost—he freely admits that on some of the models he's got, the radio receiver may provide slightly audible interference over your newfangled AAC files—but if you were born before 1984 you can probably live with it.
Most of them sell for $275 on Etsy, and some of them even come with their original (and still functional) "Tone" adjustment knobs. I never quite understood what exactly those did on a technical level, but I always liked turning them to get the music sounding just right.
