How can I obtain schematics and spare parts for my "old" Crumar? Can I have support for them?
We don't have schematics and spare parts for Crumar instruments marketed before 2008. You have to search for them on google, facebook, special websites. We don't offert support on those instruments and, generally, we don't know them well enough to be able to help. Basically, we are not the same company that used to manufacture those instruments in the 60, 70 and 80.
There is a facebook group full of information about italian electronic keyboards and instruments, they also host a lot of files: https://www.facebook.com/groups/1209164015790517/
