the line filter has 15mh inductors in it which seems like enough but im not
sure. 3amps is plenty for it. at the time my equipment died it was pulling less
than half an amp. how big should the ground plane be? my secondary is only 12"
tall. im willing to take my chances with the gas line. to get the gas to ignite
there has to be a spark or corona in a mixture of natural gas and oxygen. i
think the chances of a leak and spark at the same place same time is small
enough. if it has poor electrical properties i will look for a better ground.
what do most table top coils use for ground?
