You could try to measure the voltage at pin 12 of the CEM and see if it is the same voltage on pin 12 of the other CEM's

Hi again!
is this happening in the VCA section at page 047 of the service manual schematics file or..? (in the file section)
from the u325 4051 (CMOS demux chip ??) til the voice 8 adres line.
velosity and relative mix stil work.
so i asume the control voltage is there, only somehow its only half of what it should be..
could you explane in a little more detail what you mean ?
control signal missing that controls the volume of the cem right ?
do you think it's a minor problem ? because everyting works as it should exept that voice 8 is about half the volume.
first i have to get my hands on a scope!
looking at page 047 (if this is where the control voltages are) could you explane what to look at?
thank you! i appreciate it alot.
also, do you have experience in fixing this machine ?Message
