hi everybody,

i recently got a 707 with dead ride and crash cymbals. i took a look at the service manual and noticed that both voices share some components: There's IC25 (4013 Flip-Flop) and IC26 (5218 OP AMP)

does anyone think it's likely that one of these components is failing or do you have any other ideas what could cause the dead voices

thanks,
roglok
