Got this radio off of the internet as functional. Everything worked indeed. I've replaced all the electrolytic caps and also one of the selenium rectifier bridges.
Nothing much else needed to be done, aesthetics are okay, just a small crack in the scale.
The reception quality is exactly the same as in the "partner" model previously posted - so-so, it uses the TBA 570 IC, good on FM, close to mediocre on AM.
The sound quality is really good, It uses the same high quality speaker, although with a different amp IC, the "classical" TBA 810AS. 2 W on batteries, 4 W on mains. There's a bit of distortion at low volume though, even on battery power, quite puzzling, but considering it's not so noticeable nature, I did not investigate any further. Maybe the amp IC has been hard driven at some point in its life...
Also you can notice in the photos that they have used the same case and internals for he cassette player version too - there's a huge empty space inside - it would have been occupied by the cassette player mechanism and its electronics.
