GPO Planset conversion
I have a wall mounted planset, but it does not have the additional cradle switch to control the bell circuit (This is a different switch to the table version).
I have heard that it is possible to convert the planset telephone to work on parallel bells rather than serial bells of the original design. Does anyone have details on how to do this? Alternatively does anyone know how to use the planset without the auxiliary cradle switch contacts? |

Re: GPO Planset conversion
Hi, I have quite a bit of experience with Plansets, well at least in the past from hours of experimenting. I have produced some documents which may be of help to you. Feel free to PM me to discuss further

Re: GPO Planset conversion
Standard conversion is as follows:
