Bosch 5A is very similar to the 5 model and 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 cabinet 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 set were originally used the famous Eveready Raytheon tubes:
ER551
- ER551 - ER224 - ER247 - ER280.
