Hi,
I've been searching hard for info on the amp and it is very hard to find anything.
I guess Galanti makes/made accordians.
I am still searching for info..
Sound like you have a "rare" find
Dont get rid of it and maybe you shouldn't even use it untill you find out more.

Added...I mentioned Galanti because one site I found a picture of a Galanti duovox amp.
