There are many places to insert the resistor Ian, but anything on
the rectifier side of the filter capacitor is a waste of time. All that
does is decrease voltage regulation a needlessly large amount,
while not providing protection.
The resistor must be between the energy storage (the filter
capacitor) and the load that might develop a fault to be effective.
