Where can i buy a cathode stream tube?
Answers: An old/used TV should work, depending on how voluminous you need it. The chalice screen bit is the cathode ray tube & you'd probably entail to remove it from the frame to access the back of the tube.
Sorry, but you didn't furnish any specifics roughly speaking what you need.
You probably enjoy a cathode ray tube contained by your house but maybe not what you requirement.
Your T.V. screen is a cathode shaft of light tube itself.
