Re: [TCML] 6KVA first light
Hi Jay,
Really glad to see you putting that nice .1 ufd, 25 kVAC rated PC pulse cap to good use :-)

>Capacitor: 0.1 uf, 25Kv AC, made by Plastic Capcitors, speciically for tesla use i believe. (thank you David Reiben, this cap is sweet)
>ASRG Spark gap: 12 stationary electrodes (per side), 2 rotary electrodes (one for each side), 3000rpm max (600bps).
>Frequency: Secondary with just the bottom topload, clocked in somewhere around 84-87 KHz the last time I measured. Its obviously going to be a little lower with the extra capacitance, but I have not run the numbers yet.
