Ball bearing spark gap - where to buy?
« on: April 16, 2014, 04:07:57 am »
The flashover voltage between a separated pair of spherical conductors for a given diameter, spacing and surface smoothness is well documented. Measure the spacing that you can make the spark jump, look up the chart and there you have the kV. I want to buy a ready made one of these things for the testing and characterisation of car ignition coils so I need something that will go up to say 60kV.

Does anyone know where I could buy one of these things?

English language ebay seems to be broken at the moment.
