Hey all.
I've got hold of a Maestro PS1-a and it's very cool old phaser.
My small issue is that it's passing sound just fine, and works as it should.. just that their is a low level "Pop Corn" type crackle going on.
Is this the symptom of a dying op-amp or transistor?
How would I go about finding where the fault would be? I do have a 'scope.
Any help would be much appreciated.
Regards
Mike
