Default Speaker terminals

I need some help identifying a couple of speaker terminals, and if they could be converted over to RCA terminals.
The first photo is from a Kriesler stereo, and the second is from an early 1970’s record player.
If you can help me, thank you.

The first photos shows SOCKETS, not terminals. But they are not for speakers. Look on the back for a pair of the 2 pin DIN type. There is little point in converting to RCA Plugs, as 99% of speakers don't use them. Use DIN plugs hard wired to 42 or 79 strand speaker cable.

The second photo shows what looks like old Wander Plug sockets, probably added by a previous owner and are not recommended. There should be a pair of hard-wired leads terminating in 2 x RCA Phono plugs for each channel. From the wording you have used, I suspect you may not be familiar with older HiFi equipment, so please advise.

That's a polarized socket designed for use with a single polarized plug (note the different sized pins). I think it's more likely for use with a tape recorder rather than a speaker.

My little Decca extension speakers have unequal pin sockets like that - they came with the plugs and they look a lot like transformer taps. The ones in photo 1 are DIN of some kind - 3 in a row like that? Could be speaker connectors I suppose. I would be inclined to change them all to 4mm screw terminals rather than RCA.

The Kriesler ones look like 4 pin jobs to me.

They are a bit weird aren't they? Could even be 5 pin 240 degree! But there doesn't appear to be a key slot! Need a better picture please.

They don't look like DIN sockets to me, I can't see where the metal can round the plug pins would go into.

They look a bit like the sockets used on some car audio units in the 1970s/1980s. Every manufactuer seemed to have their own pin layout, there was (back then) a universal plug with a plastic moulding with about 10 holes and wires/pins that you put in the right holes for the unit you were using. On car audio, they were used for all the connections (speakers, +12V, ground), but here I guess they are for speakers only.

Can you look inside the unit to see how many of the 4 contacts are wired?

The first sockets:-

They were common in Australia. They are from the 50's and 60's. I even have a few "somewhere". They were also used with "separate " units, like in radiograms with remote amplifiers, they carried the power to the input and tone controls.

The second socket I have seen used in battery construction. Big 9 volt batteries from 1960 transistor radios had that dissimilar sized two pin sockets.

I hope that's of some help.

As Tony says open em up to see what's what, if your unsure post some pics. You can use a couple of binding posts or even easier to fit - banana sockets. Binding posts need a flat for them not to turn, banana sockets just need a hole drilling.

Maybe a small notch filed on one side of the hole too if the banana sockets are posh ones.....

The second photo is the type of speaker socket that Armstrong used to use on their 400/500 series amplifiers. The plugs are available on eBay, search for Armstrong Speaker Connectors.

Here is an enlarged image of one of the sockets in the first photo.
I don't ever remember seeing a socket like this before. Its definitely not a DIN socket

Very odd socket indeed.There appears to be a vague outline of a fifth pin position at 12o'clock.I remember 4 and 5 pin sockets of this type on Japanese vtr's such as Shibaden in the early 1970's used possibly for power feeds.The lack of a key for correct insertion is provided by the spacing of the pins,two close together and two wider apart with a central pin.In a 1994 edition of a Maplin catalogue a 5 pin DIN version is shown and is described as special.This one is even more so.Peter.

If it were mine, I think I'd fit DIN speaker sockets in their place. Horrible things I know, but they'd save any butchery, and are bearable if the setup is 'plug and forget', particularly if Deoxit or similar is applied on assembly.

It would be interesting if there was an Australian standard here - I note the OP is in Australia. But what did the plug look like? Not like a DIN plug presumably as there is nowhere for the shroud to go. Can you take a pic of a plug that fits, Joe?

Don't forget that DIN speaker plugs had no shroud.

Indeed they are for speakers. Here is another pic.
As for the other player, these were the sockets that came with the player. I used to have the speakers for it but they were misplaced during a few moves. I was told that they were Leslie connectors but not too sure if that is correct. The reason why I want to change to RCA plugs is so I can connect to an amp I have that takes RCA plugs.

I might add that the Kriesler came with no speakers so I can’t send a pic of the plugs. From what I remember as a kid I had a Kriesler that took these kind kind of plugs but I can’t remember if they were a 3 pin or a 4 pin

Why would you want to connect speaker output sockets to another amplifier? That makes no sense.
