I have recently purchased a West German NECKERMAN 830 record player (1960s), which requires a separate set of speakers for audio output. Could somebody tell me the technical name for this cable so that I can purchase the correct counterpart?

As others have pointed out, it's a 5-pin DIN connector.

This will carry the audio signals from the pickup cartridge to a separate amplifier with a 'phono' input. The signal levels are very low (because it's generated by the needle wiggling in the record groove) and the bass frequencies need to be boosted.* Stereo amplifiers of the period were all fitted with phono pre-amplifiers to do this. You may need to purchase a separate phono preamp to boost the signal to AUX IN levels on a modern hi-fi.

4 Left - 
2 Ground
5 Right -
3 Right +

The DIN plugs were common on German equipment. Phono plugs were more common on American and Japanese products. You may need to cut the DIN plug off ane solder on some phone plugs.

Tip: Left +
Sleeve: Left - and half the ground wire strands.

Phono Plug Right
Tip: Right +
Sleeve: Right - and half the ground wire strands.
  • The signal levels and frequency response were defined by the RIAA standard. You should see this referenced in any decent preamp.

It's a 5-pin DIN connector, probably a 180 degree version (i.e. 45 degrees between each of pins)

The corresponding socket was often found on cassette recorders of the same vintage, and the output levels will either be "phono" (very low) or less likely "line" (low) and insufficient to drive speakers without a separate amplifier.
