Re: [TCML] Tesla coil advice

["Ben Sneath" <bsneath@xxxxxxxxxxxxxxxx>]

Helo all,
that 30 cm spark length was only the javatc figure, so i
know it is wrong... i'd be more than happy to get 16cm out
of this coil...
but about the transformer: has anyone had any experience
building small hv trannies?
btw, this little coil was going to be a take-anywhere,
plug-it-in-and-get-sparks sort of thing... 
sorry for the late reply (been having computer problems -
corrupted os...)
