Greetings, I would like to ask you for help with my MRT3 zoom. a drum machine of the same brand, a more modest model, it turns out that it was working, but without sound, all the functions operational, but without audio output, I was checking and there were some rust deposits, perhaps sulfated that perhaps caused some damage, The fact is that I would like to get the schematics or the service manual, or if you could somehow tell me the values in these C65 L5 and 6 components
