On one of my radio the sound was changing higher or lower when the set was on it's face or on it's back.Finally I found that the problem was in the firts IF transformer.The cause: a free part of ferroxcube inside.Happily I have 3 Orljonocs for parts,after replacement of the first IF the radio work properly.

The link show this radio working on LW and MW with it's original batteries (1967!)

I have 2 pairs of batteries I have regenerated by charges and discharges.On the original charging block I have replaced the caps and it do a very good job with the batteries.

Note: I have 5 Orljonocs (2 in working order),all five have no output transformer (only driver)

Olivier is right.

Apparently there were at least two different builds of this radio model.

One build uses the Push-Pull stage with an output transformer; the other build uses a quasi-symmetrical push-pull output stage built around two GT108V Russian PNP Germanium transistors driven by a transformer.

I have this output transformerless radio build and I have drawn the schematics for the output stage (published here). The remaining circuit is very similar to the other build.

I have 4 Orljonoks,2 are in working order,the 2 others are out of order.On the black one the LW osc. coil was cut,I have succeeded to dismantle the coil  and sold the tiny wire,then the radio work well on LW and MW.  The schematic on the museum show 2 audio transformers,or on my 4 receivers there no output transformer,only a driver.The speaker is directly relied to the output transistors,and they are polarized by a lead betwen the two batteries cell (at 1,25V).I look for the scheme of this model of Orljonok.I have 2 working accus (dated 1967!),all others accus I have are out of order,it is miraculous that batteries can work after 50 years.The sound of my 2 Orljonok is clear and powerfull for a so little radio.On the leather case of one of them  there is a name: VOLNA.
