Vertumno
II it’s a nice little radio with a fascinating design and a
fantastic front panel.
It’s a two bands five valves superheterodyne and the chassis is
derived from the one of Alauda model.
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.
The left knob operates the power switch / volume
control and the right knob is for the tuning. The little knob is for
the band switch, it operates a two position rotating switch that
lets you choose between medium waves and short waves.
