Help a newbie put a GECOPHONE 1000 into service
First I`d like to thank the people who helped me a year ago, doesn`t time fly
As requested back then here are some shots of the insides. It says GECOPHONE 1000 on the label inside and is the same as in the second picture. So I guess it is definatly a GECOPHONE 1000 and dates around 1956. Apparently there are instructions on this page to re wire it but I can`t figure them out. I have many questions if you don`t mind: Is it just a case of buying some wire and replacing the one that goes from the phone to the socket? does the wire from the phone to receiver need replacing aswell? where do I get the wire from and what am I looking for? does the bell wire need to be attatched for the ringer to work (we have it detatched because we have broadband)? Where can I get some Baykobrite? ebay and google are failing me... Sorry about all the questions, I`m new to all this. It`s nice to see made in england on the components inside, very rare these days. It seems to be built like a tank too, things aren`t made like this anymore unfortunatly. Thanks for your help and if you need more pictures just say the word.

Loads of hits on google if you ask for Paste Polishing No 5 (the old gpo/bt description)

Thanks Nick, ordered.
Thanks David, found lots of advise on how to use it with that search term. Keep the advise coming guys. Last edited by Darren-UK; 20th Mar 2009 at 4:45 pm. |

Re: Help a newbie put a GECOPHONE 1000 into service
This page http://www.britishtelephones.com/gec/tel1g.htm implies that the model number should be prefixed by ST. Is yours?
The wire from the body of the phone to the receiver should be OK as it is. The one from the phone to the BT line is too fat to be fitted with a modern BT plug. So you could either replace it with a modern one, or for extra authenticity, retain it and join a modern lead to the end of it. You will also need to make a few minor changes to the wiring inside. Is there a circuit diagram pasted inside the phone? If so, can you take a picture? Nick. |

Re: Help a newbie put a GECOPHONE 1000 into service
If that`s the model number on the circuit diagram then it`s a KS.
Ah I think I`d prefer joining a modern lead to the end of the original, is it safe to be using this old wiring though? I presume it is otherwise you wouldn`t suggest it. Thanks for your help Nick |

Re: Help a newbie put a GECOPHONE 1000 into service
Looks like the circuit diagram has been added to the top by a moderator Nick incase you didn`t spot it.
All the adhesive had dried up and was only help in place by being wedged under a wire, so I pulled it out and scanned it. |

Re: Help a newbie put a GECOPHONE 1000 into service
Hello again,
Thanks for the circuit diagram... will get back to you when I've studied it. As for the wiring, it will definitely be "safe" so long as no bare wire is showing. Telephone wiring is generally not very dangerous anyway, with an unpleasant shock being about as bad as things could get. Nick. |

Re: Help a newbie put a GECOPHONE 1000 into service
I`m sure several of you have rewired one of these... ANY help appreciated.

Whenever your ready Nick, I`m waiting
In other news, the No.5 arrived. |

Re: Help a newbie put a GECOPHONE 1000 into service
OK, a very crude method (until I've had time to do it "properly")...
There should be a 3-core cable coming out of the phone, coded red/green/white. I presume you've got a nice new lead complete with modern plug, coded white/green/blue/red. Connect the white wire from the phone to the white wire from the BT plug. Connect both the red and green wires from the phone to the red wire from the BT plug. Leave the blue and green wires from the BT plug unconnected. Let us know what happens. Nick. |

Thanks Nick.

Can`t find anything with the BT431 plug and bare wire on the other end. Can get bare wire and BT431 plugs but the crimp tool is about £10. Would something like this do and then just cut the RJ11 end off? |

Re: Help a newbie put a GECOPHONE 1000 into service
eBay item 150330131999 would do.
Alternatively, any cable with a BT plug could be used, with whatever's at the other end chopped off. Note that the wires are often made of "tinsel wire" which consists of very fine copper strands wrapped around thin nylon cord. This is very flexible, but hard to terminate neatly. The cheaper ones are often bog-standard stranded copper wire which is easier to deal with. You may well have something lying around in your loft/garage/junk cupboard already. The colour coding of non-BT stuff is often non-standard, so let us know when you've found something suitable. Nick |

Re: Help a newbie put a GECOPHONE 1000 into service
Here's the "proper" way to do it (as far as I can tell)...

Re: Help a newbie put a GECOPHONE 1000 into service
Thanks Nick, that lead is perfect.
Is it still possible to attach it to the end on the original wire? I`d like to keep it all original looking. Also what`s the 1.8uF capacitor for and why does it need disconnecting? Just curious. Thanks. |

Re: Help a newbie put a GECOPHONE 1000 into service
It's an integral part of the phone's workings, and is part of both the bell and speech circuits. But in the "new" BT system, this capacitor is found in the master socket where the wires come into your house, and there is one shared between all extensions instead of one per phone. I think the basic reason is because nowadays, phone bells are wired in parallel whereas in the past, all phones on the line had their bells wired in series, christmas-tree light style.
