Help me identify this connector?
I'm working on restoring an old 8-track car stereo I found at a used record store.
It has this connector on the back; which is a type I've never seen before. Four pins; with both power input and speaker output in the same socket. It reminds me a bit of a DIN connector, but it's not exactly that.
It would be cool to find the male plug for this; for connecting power and audio output without modifying anything.
Is this some kind of standard connector, or is it a proprietary one? Any information appreciated!
Hi Slarti, welcome to the forum and your first post 👍,
When I looked at the socket, like you it reminded me of the DIN connectors. I remembered I had a PTV data sheet pinned up in the workshop that had a load of types listed, alas upon looking, it was purely Audio. I've got box somewhere with all manner of DIN plugs and sockets, though I suspect again they are all just Audio (no power).
It's not a DIN connector. It looks more like a type of American multipole connector.
I have had a look online at some old USA catalogs but didn’t see any that sold that type of connector.
Of course, it could be Japanese, Frank.
The annoying thing is I have seen these connectors before - in my mind's eye I can see one right now, with a cable sleeved in grey PVC connected to it - but where I can't remember, and it's so frustrating!!
Its Japanese but widely found on 8-tracks sold in USA (unfortunately it seems that the plug tends to get left in with the old car and not recovered)
red = L+
black = signal ground for speakers
white/brown = left and right speakers
L- would be the frame of the unit and/or the black cable (both could be linked but I'd personally check inside to be sure)
There was a comment on a web site that repaired 8 Tracks, they could find no 4 or 5 pin plugs and they wired them out. There were no photos of the plugs and sockets so I can’t be sure they are the same type but they probably are.
Nice detective work. Thanks for your help everyone!
My 8-track is branded EREF Electronics of Scandinavia, a company that imported and rebadged electronics from Japan and possibly other countries. The transistors in the player are Sanyo branded. So if it's a Japanese connector that makes sense.
In light of this, I think it would be very difficult to find the corresponding plug for this. What I'll do is replace the socket with a 4-pin DIN. Both sockets and plugs are easy to find. It would look pretty close to authentic, and I guess the DIN connectors are period accurate also.
An update about this 8-track car stereo!
I picked up a set of DIN-4 plug and socket, and replaced the "mystery socket". It fit perfectly, and still looks fairly close to original.
I also rigged up a high-to-low level audio adapter and a DC power socket; connected to the new DIN plug.
So now I have a pretty convenient hook-up; and can use it in my living room hi-fi!
Getting the tape deck working in the first place wasn't too much trouble. New motor belt and a tiny bit of lubrication was all it took to make it run. I found that I got some interference from the motor in the audio outputs. So I replaced all the electrolytic capacitors; and that fixed it.
So I now I have my 8-track working pretty well! These ancient tapes are another matter; I find that they usually need a little fiddling and sometimes splicing before they work. The little foil strip that is supposed to trigger the track change is sometimes corroded and doesn't work--but I had success just using some standard aluminium tape, cut to fit.
