== Reports ==
 
* Report in "FonoForum" 3 / 1986
 
 
 
 
 
* Very powerful amplifier with a beautiful appearance. Even after more than 20 years it is still a real powerhouse, but of course, like most old amplifiers, it has problems with the pots. It should be mentioned that all controls are made of aluminium.
