Mystery wall socket

Jones connector.

That's a two-pin Jones plug. General purpose connectors, not approved for household AC power, nor intended for RF. So, speaker wiring seems likely.

Hams used to use them for 12v DC so maybe someone used them to power radios and other 12V equipment and have it all backed up by a 12V car battery somewhere. As others have said, though, they could be for anything - speakers, etc.

So where is the mostly likely place to install a sound system. It may not have been a regular stereo, as in the living room, could have been mounted in the wall of the kitchen, maybe a utility closet. You might look for a square patch in the kitchen wall where it used to be. Good luck, Mikek

If a toner isn't working then try using some sort of spark gap device (a old door buzzer for example) jumper one side to one wire and a portable AM radio. Tune for the noise and follow that in the walls..

The second posting on this page is another way.

I have an old Model T Ford ignition coil that I use.

Oh, and I suggest you only connect to one of the two pins.

honestely,

Sounds like speakers. Why 3 in the BR?, unknown. The location of "corners" really makes it sound like speakers.

Don't neglect the possibility that they could be BR to Living room either. There is a small probability that one of the locations didn;t work out, and the location is a dud.

The authors look awful familiar...

This is, in fact, sci.electronics.repair, copied without attribution by another site.

That's just annoying! It costs nothing to attribute a source...

Except, there are sites that are in it for advertising money, and they steal contents from elsewhere in order to 'create" contents.

I saw it a couple of years ago during our Fringe Festival. One site came up early on searches, but all it did was agregate content from elsewhere, even changing the content so anytime "mysite.com" was mentioned it said instead "westealyoursite.com".

I have no idea if that's the case here, but it is possible.

It's certainly not uncommon to come across sites with "boards" that are actually access to usenet, but they don't necessarily say it's usenet.

I think I've seen 4 newsgroups that are stolen by various pages. One is alt.home.repair by homeowners something. Also soc.culture.jewish.moderated Another group I can't remember. And this group.

None give attribution iirc.

Not only that, but they refer to *us* as the guests!

Perhaps we should have in our signatures - Posted by Usenet - or similar and let the curious figure it out...

I'll change mine to:

First see if there's any AC or DC voltage on those pins. Then see if there's any low-ohms resistance (like a loudspeaker or amp transformer connected somewhere.) It might connect to a DIY intercom system.

Could even be telephone. Back before mid-1970s, only the rich had telephone connectors, so people might be tempted to install their own, so they could carry a landline phone all over the house and plug it into their connectors.

As others point out, could be a custom loudspeaker installation so one main amplifier can send music to many rooms.

That's a very good idea, but not to let the curious have to figure it out. We should be explicit so they can't miss it. Maybe I'll have something in a while.
