    How to "tune for maximum smoke"
    Please forgive my crude layout but it should help with clarification;

    A.C. line input---| |----3 <<< primary winding on NST
    3
    3
    neutral line -----| |---3

    No "ground" connection...
    Both caps are (were) 540-648 MFD @ 120 VAC
    The cap on the line side, after a beautiful (but short lived) light show on jacobs ladder went "BOOM!" the cap on the neutral was ready to follow suit.

    I found ONE schematic (too late) that showed two caps sharing input ground while the other lead was tied to line and neutral respectively.

    I have 3 NST's phased in parallel for 90 mA which works quite well, but you know.....

    Neon Sign Transformer?

    I have no idea what the capacitors are for?

    Please explain.

    If you put the PDQ of the XYZ inside the OFLIX before reframming, you will find the AMFM to be maximized.

    They are used for power correction.
    Most applications are only indicated when building a Tesla coil
