    Hi all,

    Can someone point me to a home made, variable power supply capable of generating voltage up to about 600V with low current (mA range). I've done a good bit of google searches and can't seem to find anything appropriate -- I've came across plenty of high voltage supplies generating 10kV - 30kV... I need something more moderate.
