2. 220 V device to 230/240 V mains: 

Device can be operated with 240 V (50 Hz).
In former times a mains voltage of 220V was valid in Germany. 
In the EU (and now also in Germany), currently a mains voltage of 230/240 V (50 Hz). 
In 2009, the tolerance threshold will be further increased. 
In extreme cases up to 250 V mains voltage can be present.
This can lead to problems during operation and to a reduction in service life.
Due to the increased mains voltage of 5% (230 V) or 9% (240 V), the device may heat up more.
increased heating of the device is to be expected. 

It is advisable to switch the device to 240 V.


3. prices according to collectors catalogue 2006 (see above) 


Condition A: 150.- €
Condition B: 100.- €
State C: 50.- €


Ebay (2008) 30.- to 80.- € (condition difficult to define)


Is offered very often and is in my opinion a very worthwhile and beautiful device
