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
This project wasnít carried out successfully, its production was very
