Dave,

you are right. It's the same matter. The rectangle output of the A-111 is AC
coupled (capacitor between the rectangle output of the CEM3340 and the
socket). This leads to problems with npn transistor input stages like the
A-117 or the A-113 clock input. There is a simple solution: the capacitor
C10 has to be shorted e.g. with a short wire or a solder blob. C10 is
located on the small adapter board that holds the 4 output sockets near the
10 pin connector. We think about replacing the AC coupling capacitors of the
A-111 by wires but have to check first if this may cause problems in other
applications.

Best wishes
Dieter Doepfer
