Connector for Wireless Gramophone Pickup Input
Is there a name for the two pin plug which was used to connect a gramophone pickup to a wireless?
I just need to know what to search for - unless anyone knows of a source. Steve. |

Re: Connector for Wireless Gramophone Pickup Input
Hi Steve,
Normally two separate plugs were employed, known as "wander plugs". Not terribly easy to come by, but there are workarounds. Do a forum search Nick. |

I believe John Birkett in Lincoln still has some wander plugs but Lincoln is quite a long walk from the Isle of Wight. Perhaps if you phoned him he would post you some. 01522 520767

You could use 3mm split pins, solder the wire and cover with shrink wrap.

Re: Connector for Wireless Gramophone Pickup Input
Would banana plugs fit the sockets, if so, here's the link to my post about modern made but vintage style ones I got on the t'interweb-a-thingymajig.

Re: Connector for Wireless Gramophone Pickup Input
As far as I know, wander sockets are 1/8" and Banana 4mm, 4mm is also the size of some European mains (unshuttered) sockets. And no surprise Banana plugs are quite difficult to get on the continent.

Re: Connector for Wireless Gramophone Pickup Input
You might be able to use the L and N pins removed from a BS546 3 pin 2A plug (or a 2 pin 2A plug if you can find one) as they are are 1/8" diameter. An old plug would probably be best as they often have split pins, whereas modern plugs have solid pins and rely on the socket contacts to provide resilience. The old Wander plugs usually relied on a split pin plug engaging a socket which had a non-resilient uniform diameter tube, although I have come across wander plug sockets having resilient contacts.

Re: Connector for Wireless Gramophone Pickup Input
There are 3mm Banana plugs about, at a price which will fit wander sockets quite happily.
Matchsticks are cheap

Re: Connector for Wireless Gramophone Pickup Input
1/8" brass rod, slit down the end with a slitting saw blade? Cut a thread on the other
end and make a screw-on cap. Philips had 2 (active) pin connectors for this I think. They had a dummy pin in the middle, either round or flat. There was a convention that one was for outputs and the other for inputs, but I can't remember which was which. |

That's what is currently being used! I did find a strange BS5733 mains plug which has three pins 2mm diameter. Removing the centre earth pin allows the other two pins to fit into the input and the fact that they are slightly closer together makes them a good friction fit so this could work. However, I have a CNC router and a 3D printer at work so I think I can do better! Steve. |
