This CRT dates back to 1960s monochrome Television. Not many of these CRTs still survive today so it is nice to fine one to play with. It is being tested here and setup as a rough oscilloscope using deflection coils, whereas electrostatic deflection is normally used in oscilloscopes. To achieve this, beam-blanking or Z-modulation is being used and this is essentially the same for both TV and CRT oscilloscopes.

Caution: Implosion and high voltage shock risks are present when working with CRTs
