Catalogue Nos. T103 (Type 1760) and T104 (Type 1761)
The PyeTMC magneto telephones are a development of the 1746 automatic telephone instrument currently in use throughout the world. They retain the attractive and modern design features of the 1746 and also provide the latest highly efficient receive and send characteristics.
Calling in the 1760 and 1761 magneto telephones is provided by a solid state ringing current generator which is powered from dry cells. The telephone and generator are an integral unit. Operation of the ringing generator is by means of a pushbutton which replaces the more usual crank handle associated with earlier models. The generator fitted in the type 1760 has sufficient power to ring up to four bells in series or two bells in parallel at the end of a 1000ci line, whereas the type 1761 is equipped with a more powerful version capable of ringing up to ten bells in series or four bells in parallel also at the end of a 1000c line.
Both telephones are supplied with line cords wired to terminal blocks. The 1760 telephone has a four conductor line cord and the 1761 telephone a six conductor cord -enabling an extra extension to be easily connected.
The design incorporates printed wiring boards and the use of modern miniature components which provide utmost mechanical and electrical reliability. Ease of servicing is ensured by the simple internal layout. Whilst fully compatible with existing magneto systems, this telephone has the additional advantage that it can be converted into a central battery or automatic telephone if required.- Also a direct line connection between two telephones may be arranged.
