[AMRadio] More Boring Voltage Regulators

[Joseph Bento]

I don't recall what the equation was for a spark gap and voltage 
breakdown.  I'd feel a bit leary of using a 16pin header with 500 volts 
applied though.  Considering theat the pin spacing is .1" there's not a 
lot of protection for flashover.

Using solid state regulators for high voltage is fine, but I'd be more 
inclined to build the circuit on a terminal board, or etch a PC board 
for the regulator, using wide spaced traces.
