There are CRT tester equipments. But knowing some marqees ate tubes without noticeable wear on them (due to the high heater voltage) and looking at the cut HV cable is not very promising for me... _________________ NEC 6PG xtra

Cut HV cables, or purposely damaged electronics is always a sign that a technician somewhere has deemed the item to be defective, and the cut lead indicates that the item is bad, and not to use it.
Now, there's many a time that a 'technician' is wrong, and the tube may be fine, but chances are even if the phosphor is good, the tube may have no emission, it could be shorted, etc. About all you can do is put on a replacement HV lead and try the tube. Even the ones with wear have some value for the LC housing, and esp. the green C element.
