In 1956 there is mention of the Gecophone K or Gecophone 1000, which used an identical case to the Gecophone but having a more modern handset, with no spittoon and updated internal circuitry.  There is no indication that any of these were sold or produced in any number.  The pictures available were probably field trial pictures and it is thought that this model was dropped in favour of the new desktop telephone, the "1000 Telephone".  The next Gecophone model, called the "New Gecophone" was produced in 1959 and was identical to the plastic telephone used in the UK by the GPO.

Major changes to this Gecophone were the handset, a 4 way handset cord,
new Induction Coil, two capacitors and a 5 way terminal strip on the base plate

 

One capacitor is on the base plate whilst the other is squeezed into the body
The feet are also a push fit

 

Conversion to Diagram KS10915

To convert to UK plug and socket use a BT line cord and wire as follows:-

  1. Remove and discard the old line cord.

  2. Feed the new line cord through the casing entry hole and tie it or knot it to the metal loop inside the phone.

  3. White wire of line cord to Bellset terminal 2.

  4. A 3.3k resistor fitted between Bellset terminals 2 and 3.

  5. Red wire of line cord to terminal Bellset 4.

  6. Blue wire of line cord to terminal Bellset 5.

  7. Green wire of line cord - spare - connect the Bellset terminal 1.

  8. Disconnect one of the wires on the 2uf capacitor and insulate.

  9. Fit a Rectifier element across the receiver on telephone terminals 7 & 6.

  10. Check transmission and replace transmitter if bad - Click here for more information.
