Doepfer

Hello, 
just to be shure:
can i run the A-188-1 BBDs on +-15V ?
Does this maybe also increase the Headroom of the BBD IC ?
( it distorts quiet fast )
oh, i read the doepfer instructions about Doepfer on 15V, but those
BBDs are to expensive to not to be very shure before i put them into
my other Rack ( which has no 12V supply )

thanks,
H.
