Need High voltage caps and diodes

[Fucian-at-aol-dot-com (by way of Terry Fritz <twftesla-at-uswest-dot-net>)]

Hi, does anyone have or know where to get very cheap capacitors rated 10-15kv 
at 100-1000pf and diodes 15kv-20kv5-10ma100ns very cheap?Theyre for a 
multiplier which i will experiment with a tesla coil and see about directing 
the spray above the toroid and seeing what happens!Can these pieces be gotten 
cheap?Like 1.00?One place sell 10kv 1000pf disk caps for 1.00 but i really 
need 15kv and diodes are only 6kv.I plan on powering the cascade with a small 
flyback putting out 1centimeter of plasma.Is that too much for a 6kv 
diode?Any help is greatly app.,
