Hi Welcome to the reason a lot of us don't have running Cs standards.
There is a very basic wear out mechanism with Cs. Once it's moved from one end of the tube to the other, the tube is dead. There is no practical way to rebuild the tubes. Running one will simply wear out the tube. They are a very expensive toy to keep working.
