Re: NST protection circuit

Hi Will,

They should be 100 watts but you can use 50 if you are running say 100mA or
less.  I made them big resistors to stand off voltage and to keep them from
getting super hot.  Power resistors like these have a surface temperature of
about 350C at rated power.  They are just heating elements...  Most people
thought the resistors were getting too hot (they were fine) so I just used big
resistors to keep them from getting really hot like they tend to do normally.

Cheers,

        Terry
