Ivalek is made in England.
The
cabinet of this radio is similar to the one of tube radio but it’s
smaller.
This
version works with crystal detector, on the bottom there is a hole
through which you can see the crystal.
The
pointer of the detector is mechanically connected to the little red
knob that you can see in the front side of the radio.
Looking
through the hole it is possible to place correctly the pointer on
the crystal, finding the most favourable condition for a good
reception.
I
found this radio in his original box.
