Help Identifying a Plug/socket
 

I'm hoping someone can help me identify (and thus hopefully find a
replacement for) a plug used inside an aged hi fi loudspeaker.

Specifically, it is the plug that attaches the signal cable to the
chassis of a Tannoy 15" Monitor Gold "dual concentric" driver
(i.e. the tweeter is mounted at the centre of the bass driver).

Wiggling that cable has revealed a fault in either the plug itself or
in the cable just back from it. "Dry Joint" comes to mind. But
the plug is awkward to disassemble --- it is held together by bending
lugs over some kind of fibrous plate that has the actual pins in it
--- and I'm worried I might damage it.

I'd like to replace it with a new plug. But I can't even look for
one, because I don't know what this type of plug/socket is called

The socket is round, and roughly the size of a finger nail, with four
places-for-pins-to-go arranged in a "slightly tapered square" (i.e. the
plug will only go in one way round).

The plug itself looks a bit like a short, fat coax blug but with
(obviously) four pins!

I've found a photo of the driver at...

http://www.oldhifi.com/tannoymonitorgold.jpg

The socket for the plug I'm talking about can be seen on the chassis
of the speaker, about 80% of the way down the centre line of the photo.

Can anyone tell me what a plug/socket of this type is called? And
where I might be able to get a replacement plug?

Robert.

I have a vague recollection of them but can't remember a name.

They're extinct now ! You'll have to replace both the socket and plug. A good
thing since it's was lousy choice for the job in the first place.

They were also used for dry batteries on portable valve radios where the
one battery supplied both heaters and HT - so was two in one.

McMurdo used to make those. They were used in a number of stereo systems here
in Australia in the 70's. No idea if they are still available anywhere, or what
they were actually called.

You may be able to solder wires to a couple of split pins of the right size
to make a connection.

Heat shrink could ID and insulate them.

They're easy enough to repair or re-use.

Carefully bend back the lugs on the cover and remove. The pins are hollow
and the wires soldered to the inside. The base is fibre and not easily
damaged by the heat of an iron - unlike many modern plugs.

More likely one or more of the four sockets have increased in diamiter and
caused a loose fit.
they consist of a rap around contact.
If you could get to the other side with long nosed pliers
(I have a pair that are curved )
you might be able to give the contact tubes a gentle squeeze.

Molex pins come to mind for this..

The UK made a type of mini banana plug which used split pins.

Looks like it might compatible with an Amphenol "Minature Plug",
Like the number "71-4S". This is a bakelite shell with pins molded
into it. Much cheaper versions existed.

Buzzwords: "Type 71" or "Type 91" plug. Also matching were the
"Type 78" sockets.

3/32 inch pins, according to some old catalogs I saved from my youth.

Obsolete plug/socket no longer available (unless from surplus).

Overkill. I'm sure the shack has speaker connectors that would fit.

The problem might be how much they extend behind - so as not to foul the
cone.

Sure, but ISTR some 'lift spring' types that could work.
