SAGEM SPE-5

Technical data

The SAGEM SPE5 is one of the most famous teletype used by the French PTT operated TELEX networks.
The 'E' letter stands here for 'electronic'. This model was replaced by the SPE5A in the 70's.

This model evolved from the fully mechanical SP5 one to become an electro-mechanical device using dedicated TGN-A and TGN-B germanium transistors.
It can work on either 50Bd or 75Bd speed by modifying the gearing.
Optional Tape Reader and tape Puncher units can be seen on the left and right side.

The unit pictured here (dated 1965) is the one using the external -48V supply box unit which also allows for the line testing and local echo.
It has been modified in order to handle the 45.5Bd speed used in the Ham networks by slowing the shift register clock and to allows for switching off the motor after a 30s idle delay.
A local power supply was later added with a dedicated power transformer.
