Casio CZ/ VZ/ FZ - Pro Series

Hi everyone,

after having read through the variuos posts in this forum,
I am pretty sure that I have this "classical" relay problem.

In theory I understand what needs to be done, but where can I find the relays? How can I indentify them as such? How do I bypass?

The synth works otherwise and I could get some really great sounds out of it - would be great to get it to work properly again!

Thanks for your help!
