Some links about driving an oscillooscope cathode ray tube.
- The most popular schematic, from Elextronixandmore, using a Hammond transformer. A kit can be bought at Catahoula Technologies. The schematic and the BOM are here.
- Another solid-state scope from Electronixandmore, without isolation. The voltages are the following:
HV 350V Anode Cap X1/X2/Y1/Y2 280V Deflection plates A2 270V Anode 2 A1 -310V Anode 1 K -665V Cathode G1 -675V Control Grid
Those values are fine for a 3BP1 tube.
