Kevil: you didn't say what you neaded the resistors for or what current.
High voltage resisrors are expensive. You can use series resistors, surplus
resistors, or even small black rubber hose if current is low. Auto ignition
coils put out about 30KV and can be transistor (RCA 40411) driven or FET
driven from a battery.
