I’m looking for the schematic diagram for the EWI 3020 Controller.
I purchased mine way back in 1990 and it has developed a problem where the pitch jumps around. I’ve tried to adjust the trimmer and have had some results, but the pitch still jumps around.
I’m beginning to think that it’s a bad trimmer capacitor.
Has anyone else had this problem…
Thanks in advance.
