Earlier today I was fitting a 5pin DIN plug to a length of cable terminated in two Phono plugs, and, having a couple of good quality metal bodied DIN Plugs handy, thought I might as well use one of these rather than a cheap plastic plug. When I came to insert the plug into the 5pin 180 degree socket on the back of a record player, I found that, even though I made certain the plug was fully inserted into the socket, there was no connection between the plug pins and the socket. No obvious reason why, except that the socket is one with wire wrap terminals.

Is it not a case of the socket pins being split like some valve socket pins do?

From your description I am mystified why the pins on a DIN plug do not contact a DIN socket.

The wirewrap socket is a new one on me, I've seen PCB mount as well as conventional solder tags but never w/w.

Is it possible that its not fully mating?

This socket is in an Amstrad RP33 which must be getting on for 30 years old, Ian, so DIN sockets with wire wrap tags go back a long way. Having tried an identical new DIN plug in the socket, which did make contact succesfully, I wondered if, when soldering the leads, I managed to distort two of the pins. In the end I bypassed the DIN socket and wired in a twin phono lead directly.
