ryan,
good to here from you again, i started thinking the worst because of
your absence. i can offer two suggestions, start building the largest
salt water cap bank in the world, lot of bottles, lot of space, lot of
salt. or start building a flat plate cap bank, 19kv for a bank of
seriesed paralleled flat plate caps would not be that expensive or
difficult, just time consuming.
if you would like some suggestions and such, mail me off list. remember,
mmc's are not the only form of capacitor for coiling, regardless of what
is now being insisted, many coilers used home built capacitors before
mmc's and emmc's and they made sparks. the six bank flat plate units i
have right now could be duplicated and reconfigured for a rating of 432
nf -at- 18kv, all for a cost of $80.00. and this cost could most likely be
lowered. also, do you have enough turns on your primary so that you can
tune it with the present cap? are you using a static gap?
