- Most of the Xerox high voltage supplies will only put out less than 10
- milliamps. I`ve found them useless for jacobs ladders, but they can be used
- for operating short lengths of neon tubing. They really only work well with
- green tubing of small diameters, like the kind used in beer signs. For a
- Jacob`s ladder, try using an ignition transformer from an oil furnace.
