I just finished total restoration of a mkII axxe and everything works fine now except that every key makes audible click on the audio output even with nothing routed thru the filter and filter cut, and even with slow attack adsr … i don’t have this problem when keyboard is in keyboard repeat mode (except always when i trigger a new note, the “repeated” ones don’t have this problem) … seems as if the gate was leaking somewhere … any idea ?
I discover that the supposed cd4011a was at one time replaced with cd4011bce … is it a direct replacement ?
Hi, I’ve solved the unwanted click by putting an 1M resistor between J1-1 and C14; place it close to J1, because perhaps the trigger track causes induction with near tracks.
