Forgot to attach the update.

While checking out various design for PSU's I noticed one person remarked that he might move the Varistor put the varistor after the 47R, so it doesnt have to short out the power station on spikes, same with the 20M resistor.
He also suggested he would not use a 20M but a rather an attenuator, say/guess 220K and 5k to ground.
Any thoughts around this statement ?

PLEASE NOTE - I have also added a WARNING for anyone who might stumble across this !!

Kind regards

Dennis
