I've got a silkworm machine that has a scratchy audio issue. I've cleaned all controls and connections and I've tried a different pcb. The audio was fine with the other pcb. I'm thinking that it must one of the dozen or so caps in the audio section of the pcb or one of the ic's. Attached is a pic of the audio board. Any ideas?
