My capacitor is .019 micro farad and max spark length measured point to point is 62". The 62" must have been on a good day. Most of the time max spark length is 50 to 55". The output seems to be greater on very cold days. > > Malcolm > > > Date: Mon, 03 Mar 1997 15:01:47 -0700 > > From: Dave Burman <dburman-at-ix-dot-netcom-dot-com> > > To: Tesla List <tesla-at-poodle.pupman-dot-com> > > Subject: corona > > > <snip> > > > > My coil configuration is as follows: > > > > 2 15kva neons > > 2 air wound and 2 ferrite core chokes > > copper tube vacuum quenched spark gap (8 tubes, .030 spacing) > > Primary -1/4" copper pipe with 3/8" spacing 12 turns > > Secondary - 6" acrylic wound with 22" of 24ga magnet wire > > Torroid - 4" dryer duct around a 24" pizza pan > > ground - very heavy welding cable (1/2" dia) connected to 1 8' copper > > plated ground rod > > > >
