Hi Bob,
Great videos!
I got much the same entering 125 volts, 60 Hz, 93 Volts, 0.30 Amps and 10 volts gave me 11.24uF. I see the Brits are also assuming a surge limiting resistor of 33 ohms 3W which is probably a good idea. That would reduce the required reactance from a pure capacitive dropper but I still think I goofed in my calculation. I like the idea of using a motor run capacitor and the spread sheet is useful. They calculated 107 ohms also. (106 - close enough)
How is your 38-7CS chassis coming along?
