    My fluke only measures capacitance to the .0x if i put it on manual, if i leave it on auto it displays 2 for both of them so until i get a better meter on them wont know for sure if they are good or not but i may go up and buy another 330 for cheap and see what the caps look like in that one

    The post above is missing a zero. The miller part number is 10kV.

    This site has an impressive assortment of them:

    ... But the high voltage ones are just as much as the miller part.

    These are only 5kV, while the miller part number is 10kV, but I don't know how high it's actually running them:

    Are you able to measure the capacitance on those capacitors?

    Yup, that’s what mine look like. More schmoo on mine though.

    Sorry i just seen that the cheap cap is one more 0. I read it as .0024 not .00024 so yes that will not work, but im going to keep searching

    Heres the pic of the dripping from the caps going to remove and inspect behind maybe they were already replaced

    Ryan your saying that the same mica capacitors in your machine have dripped resin? Ill have a pic up of mine in a sec

    The 10x less capacitance is a bigger deal and may not work. The value of that capacitor is important because it is tuned for the HF coupling coil for the right frequency on the system.

    Yeah i get the .0004 difference but thats why im here to see if anyone smarter than i can confirm that it will work or that it wont.. currently the hi freq starts the arc just have to be pretty close for it to jump. It was just a quick test when i picked it up. Once i get everything cleaned and re set the gaps ill take pics tomorrow and post them up of the hard resin? That is/was drilping down the board from behind those caps on thr hi freq board

    But that's the wrong value--it's .00024. The "4" on the end probably isn't a big deal, but it's ten times less capacitance that the .002 that's in there now--I would not go there.

    $3.50 is alot better than $150 from miller

    I was thinking of trying these

    What was the new part # i just picked up a 330 with the same cap(2 of them on the hi freq board that are leaking) would like to replace them, the 330 starts an arc still but just would like to replace them as im sure its not long before they cause a problem

    Fantastic! Way easier than trying to adapt some other part.
