	A Small Cautionary Note:
	For many years "pole pigs" were filled with an "oil" composed of
	PCB's.  PCB's are carcinogens.  I would be VERY careful of such.
	(They may be called other things: askarels is one.  They may look like
	"oil".  But "most" are PCB.

	Yes but....  The catch is that the stray capacity will lead to the
	primary sides starting to try to "float" to higher voltage, which can
	lead to breakdown, and "letting out the smoke".  Where such things
	are done, great care is needed in how the primary sides are handled.
	Or be ready for smoke....

	It can be done.  But its tricky.

>I have a couple of large .04uF, 80kV DC
	Such capsa re almost always good for AC, at that voltage, tho the
	labelling may be for DC.  Electrolytics are the only "really DC ONLY"
	caps and they do not exist at that voltage...

>rated caps
	1) See above on PCBs.  PCBs were used as insulators or "fillers" pr both
	in HV Caps as well as transformers.  Caps, if "good" will not leak, but
	....

>that came out of an XRay generator and I was wondering if these would be good
>for Tesla coil work?
	Would need to know more.  They  would be better than nothing, tho not
	so good as caps designed for the work...  If i had them in hand, i would
	use them,  if the values are in the range and they are not leaking.

>They were used to filter the high voltage DC output to the XRay tube, so I'm
>not really sure if they would be good for pulse work? 
	There are better, proably, but they will work...
