Tirteo is derived from the Alauda model, it has the same chassis and the same electrical diagram but has got the tuning dial and the case is in a different shape made.

Itís a reflex superheterodyne which can receive only the medium waves and the volume control operates in the antenna circuit.

The filaments of the valves are connected in series and the power supply is made by a little autotransformer which operates the mains voltage adapter also.

This project wasnít carried out successfully, its production was very limited and today is hard to find it.
