Bosch 5 was manufactured when the Italian Radiomarelli and American Bosch
were business partners.
At that time the Italian company started the Coribante production on the base of this radio.
The
wood case is most simple and sober than the Italian version, but
just look at the chassis to understand that (apart the transformer)
the two radios are very similar.
This set has the standard broadcast band only and works with direct
amplification coupled cascade stage circuits.
In this radio were originally used the famous Eveready Raytheon tubes:
ER551
- ER551 - ER224 - ER247 - ER280.
