Description:

This is a Swedisch model of the Philips tube radio's in the late sixties. Not exiting, but usually the quality is very good.


Repairs:

No repairs are made. All the components are in good condition. There are polyester capacitors build in, which have a very long life time.


Performance:

Performance is good, sound quality is good, but the reception of the FM broadcast station could be better in my opinion.
