Yamaha CS5 volume problem
Hi everyone new user long time reader.
I have a problem with my Yamaha CS5. All of a sudden it has gone quiet. If I crank up the amplifier on my mixing console way up I can hear it and it behaves as it should. Only the volume is like a tenth of the normal amplitude. Has anyone had similar problems?
Ive had it for maybe 10 years and apart from changing a key it has been a rock. And I love it dearly.

Upon opening it up there are no apparent problems (blown caps or swelling) nothing looks wrong.
I can see that some previous owner changed a few caps but since it has been working fine that would probably not be it.
I found a service manual online in japanese so following the instructions are extremely hard. Anyone have it in english?

Since it still makes sound albeit very shyly I wonder if something might have happened with the VCA. I can still turn the volume up and down on the initial level and every other pot makes the apropriate changes.
Thankful for help since the nearest repairman is 70km away.

Never mind after cleaning it and bending a suspicious ceramic cap it healed itself. All is well again.
Curious as to what all the VR pots do. Anyone who can shed som light on this? :facepalm:
