If you are experienced with electronics thats possible. You have to
interrupt the internal A-152 addressing (three address signals A0, A1, A2)
and connect the three address signals to the corresponing pins of the A-154.
Some soldering is required as you cannot use the high voltage address
signals (0/+12V) of the A-154 which are available at the socket that is use
to establish the connection to the A-155. Instead of this the internal low
voltage address signals (0/+5V) of the A-154 have to be used.
