We have a Christian school here in town with an ADC 2000 in their auditorium. Lately it has a keying problem where several notes may not play up and down affecting all three divisions.
The problem comes and goes, however when it occurs you can hear faintly in the background what sounds like several keys being mashed down all at once. The sound is fairly faint in the background but is always there when the keying problem is present.
I have replaced the KA-1 board already, so I am inclined to believe the problem may be in the MUX board. Has anyone else experienced this type of problem and have some suggestions where I might look.
Bye the way I have checked the power supplies and they seem to be in order.
Any suggestions will be greatly appreciated as I know very little about these organs.
