Hi All, I made a nice little AC milliamp meter to test neons and measure the neon current to my coil. It is real tough, shielded, and has excellent RF rejection. It is surprisingly accurate. Cost is about $35 if you buy all new parts. The details are in a 300k JPG file at: www.peakpeak-dot-com/~terryf/tesla/misc/meter.jpg Cheers, Terry
