Fellow VG owners,

We have been occasionally blowing the fuse in our source control unit over
the past year and getting an error message "source filament in limit".  We
would replace the fuse and were right back in operation.  This week we blew
the fuse and got a new message "faulty source suppressor".  Now when we
install a new fuse, it blows almost immediately and we are back to the old
error message "source filament in limit".  I'd appreciate any
ideas/experience anyone has regarding this problem. My fear is that I am
going to have to replace an entire board (which I don't know how to get a
hold of). Please say it ain't so... 

Regards (and Happy Holidays) to all,
Margaret
