Hello all. 

I have a friend who has a studio who is Looking for a talkback system Battery for an AMEK MOZART 56-channel console, and I thought  that someone here might be able to point me in a good direction to begin searching.
If you have any advice on where to begin my search, I'd greatly appreciate it.

I am also interested in finding the Manual for the AMEK MOZART 56-channel console, so I can see if there is a part number for said battery.
Thanks!
