403 is the second model of the SOKOL series.
It does not differ much from the first model.

It changes slightly aesthetics and the aerial socket is located in the rear side of the radio.
This model has the tuning dial glass made too and it is powered by a 9 V. rechargeable battery.

Some of this sets have the same adapter of the oldest SOKOL, others have a most simple adapter, which work with a resistor / capacitor voltage reducer.
In this SOKOL model, the trade mark is shown only on the box, not on the radio.

Looking at the photos we can see the images of two identical radios, one marketed by TENTO, the other one by MПИ (MPI).
