I've just started a turntable refurbishment (more details later if it works out) - one of the things I want to do is replace the arm lead of a Stax UA7 arm. Are these things standardised in any way? I suspect that it's a plug/socket arrangement common to many Japanes arms of the time (1980-ish). Looks somewhat DIN-ish, 5 pins buried up in the arm pillar and sockets in the plug (if you see what I mean) - barrel diameter is about 12mm.
