Hey all,

I came across a capacitor and I have no idea if it will be good to use in a
tesla coil.
I have no way of getting info on this cap and I have only one.
The label is as follows:

SPRAGUE
POWERLYTIC
36D123G040BC2A
EP40-123
12000-40DC
74  47 L

If anybody can get any info about this cap it would be great. Once again I only
have one so I will need to know where to get more if they are suitable for a
TC.

Thanks,
Lance
