GEC
TEL/61K/ATS

GEC table phone.

This telephone is very similar to the GPO Telephone No. 706.  The only difference is that the regulator has no regulatory components on it.  This is most probably to cheapen the telephone as it would have be used mainly on private telephone systems in the UK.

Inside the phone there maybe a circuit diagram marked Telephone 1100 type.

Circuit diagram for this telephone is KS13418.
