Very early Germanium transistor.
ATES (Aziende Techniche Elettroniche del Sud) was formed in the 1950’s to provide electronic components for the Italian government-operated telecommunications company S.T.E.T. (Societa Finanziara Telefonica). Ates was a subsidiary of Siemens, licensed to use RCA technology, and produced many germanium transistors. In 1971 the Italian government decided to merge SGS with Ates to form SGS-Ates, these parts bare the ATES logo only, which would suggest they were manufactured prior to 1971, the only markings on them where one would expect to see a date code are the numbers 5 0.

PLEASE NOTE!
These parts came to us as part of a lot of surplus stock from a large ‘Milspec’ type Co. and have been kept in storage for some time, we have therefore classified them as ‘new other’. They are however in good serviceable condition, stored with us still in their original packaging, the photographs are representative of their general appearance, being of some of our actual stock, and, as with all our products they come with a full guarantee.
If you have similar items to this, or indeed any electronic components that are surplus to requirements please contact us with details.
