Original poster: "Gerry Reynolds" <gerryreynolds@xxxxxxxxxxxxx> Hi Dest, (is that better?)I believe both the primary and secondary have both frequencies in them. Its not a case where the secondary takes on one frequency and the primary takes on the other. If both frequencies are in the secondary and a "full" beat period occurs (and lets say there is no decay in this period of time) then the beat envelope could aggrevate the voltage gradient to cause a racing arc. That's the premise this discussion is based upon.
