<<                     ----------------------------------------
         Hate to make you the target of my ire, Ed (especially you),
         but I see this same foggy-bottomed thinking again, and again
         (and again!) on This List:
 
         -- If a capacitor is rated "X-volts, ac" that is r.m.s. volts
            and  =not=  peak volts!   So your 20,000-v. capacitor is
            good for 14,144-v.  ( that's 20,000/1.414 ) -- but not
            quite.
 
         -- Capacitor manufacturers have  =forever=  played fast and
            loose with voltage specs.  It is therefore  =essential=
            to de-rate mfg'rs. specs. before applying any capacitor.
            (One sees the same thing in other areas of industry --
            auto makers' horsepower specs., for instance.)

Robert,

First of all, I have worked in the electronics industry as a "working
engineer" for most of 18 years.  These capacitors were designed and
built by
Condenser Products specifically for use in a Tesla tank circuit.  The
rated
AC voltage on the caps is for the high voltage supply to the tank
circuit.
 After discussions with C.P. about the first cap that I lost, their
reply to
me and I quote " In reviewing your application 15,000 V rms at 500
milliamps
is not excessive for this capacitor".
