Make links to this great museum of old russian radios from the 1930s-'60s. The most intriguing is this image (from the 'Author's exposition in Karelian State Museum' section) of a reel-to-reel tape recorder apparently powered by a vinyl record player. The full pic shows a microphone and some kind of control box/power supply. Anyone know anything about this? More to the point, anyone want to reverse engineer it and create some kind of awesome vinyl/tape DJ setup?
