Scott, I'm not sure how late a model you have but on the A15 board you should see a place for two resistors that are connected on the board in parallel. If you connect a high resitance decade resistor (start at 10Megs) across one of the resistors. Now while monitoring the EM divided voltage reduce the decade resistor until the EM test point increses to .25VDC. Now solder a 1% resistor of this value across the one of the other existing resistors. Now you are set up for 2500VDC EM voltage.

Ah, I do have the 2 resistors on the A15 - I do have the late model oven controller so my ionizer shoud be DC correct? Now the only problem which remains is the sourcing of a spare tube - Scott On Tue, Sep 30, 2008 at 2:58 PM, corby d dawson <cdelect@juno.com> wrote: > Scott, > > I'm not sure how late a model you have but on the A15 board you should > see a place for two resistors that are connected on the board in > parallel. > > If you connect a high resitance decade resistor (start at 10Megs) across > one of the resistors. > > Now while monitoring the EM divided voltage reduce the decade resistor > until the EM test point increses to .25VDC. > > Now solder a 1% resistor of this value across the one of the other > existing resistors. > > Now you are set up for 2500VDC EM voltage. > > > Corby Dawson > ____________________________________________________________ > Click here to become a professional counselor in less time than you think. > http://thirdpartyoffers.juno.com/TGL2141/fc/Ioyw6i3oJtoeZD8bdFl3HM6Qnrf4dkHES7UXgr2gqDl1I14G8tilHb/ > > _______________________________________________ > time-nuts mailing list -- time-nuts@febo.com > To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts > and follow the instructions there. >

You mentioned building a -3500 volt supply - why not use one of the Ion pump supply units?
