DC power again

["Tesla list" <tesla@xxxxxxxxxx>]

If a DC power source is used to power a Tesla coil the firing rate of the
spark gap will depend on the charging time of the cap, rather than be nested
around the line frequency.  Thus, when a DC source is used, the size of the cap
can be traded off against the number of sparks per second . (I am assuming that
the firing rate of the spark gap is set much lower than the line frequency so
that the effect of the ripple in the DC current can be ignored.

>From what I have read a larger cap in a properly designed Tesla 
coil will yield
a higher voltage and thus possibly a longer spark.  If I increase the cap while
also suffering a decline in repetition rate will the sparks actually 
get longer?
 Is a high rep rate necessary for long streamers?

I have an old Xerox machine transformer, 13kVDC @ 300uA.  With a 0.01uF cap
charged to 6kV, the rep rate will be only about 5 sparks per second.  Will this
work?
