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.

thanks for the confirmation about the problem !
best,
