Hey Mel, sorry about going back to this dreaded topic again but I was wondering a couple things about your transformerless power supply circuit.

1 - What sort of 470nF 400V cap did you use? I can't seem to find a suitable one down here in my funny little country.

2 - Is the voltage dependant resistor an integral part of the circuit or a somewhat optional component?

No more questions on this subject after this I promise.
