content: Looks like an ordinary chassis mount female DIN 41522 loudspeaker connector - common as dirt in 'rightpondia'.Edit: BradC beat me to it.

content: I think I first came across those in the 70's ... and I never did like them much as speaker connectors. The pins seemed a little inadequate, especially the smaller one and there was no real "feel" of a solid connection.I would get uncomfortable with the thought of anything more than 1A running through them, but with 8 and 16 ohm speakers being common back then, this translated into quite reasonable domestic listening levels.Still don't like them much.

content: I recognize the RCA jacks but "DIN" says nothing nowadays (thought DIN was a rounded pin configuration..). Anyway I needed an ID, as in part number or source. This is in pristine condition and after re-capping, it should fetch more $$ if I include speaker cables with the jacks.

content: Just search for "DIN speaker cable".You'll get more hits than you can handle.

content: 2 pin DIN was always the oddball of the range. You're quite right that the rest had a circular outer "screen" with pins arranged at regular intervals round a circular arc (except for the few that didn't!).

content: DIN stands for German Industry Standard ( when translated to English), and refers to a standardised diameter of the cutout of the sockets and a common diameter of the corresponding plugs. You had almost an infinite number of variants, with number of pins, position of pins and angle of arc between the pins being the differentiator between them, designed to be almost fool resistant.

content: Quote from: Benta on August 25, 2017, 10:30:53 pmYes, the only one which was rated for more than 1A, 2A IIRC for them, though you could do 5A for short periods with little ill effect. Much loved by European electronics manufacturers, especially B&O, who loved them, along with SCART connectors.
