Building a Voltage Multiplier Cascade - Vacuum Tube Tester (2)

Part II of the Vacuum Tube Tester - Series. Teardown + Voltage Multiplier Cascade. To clarify why I used 2.4kV instead of 2.0 kV in my equations: The Bosh capacitors would all be able to handle 300 or 600 V. It's the "dish washer motor capacitors" that are the limiting factor. They only have a DC voltage rating of 500 V AC . I therefore will have to inform myself what that exactly means and what DC-voltages they are rated for. My estimation is that they can handle 600 V DC. Therefore I think that 2.4 kV (4*600 V) are still a realistic maximum output voltage. The potentials at the nodes in the lower row are then: 600V, 1200V, 1800V and 2400V. Should one of the dish washer motor capacitors fail, will I replace all of them by higher rated caps.
