Hello All, I am looking to ballast my new potential transformer. I came across this idea (http://hotstreamer.deanostoybox.com/mnovak/ballast.html) of using 1/8" welding rods inside a 2" PVC wrapped with 500ft of stranded 10awg THHN. Seems cheap and functional. You can add or remove rods to alter inductance and raise and lower the core as well. I wonder if there are any other equally cheap/good or better ideas? Thanks, ~Dan Kansas City area _______________________________________________ Tesla mailing list Tesla@xxxxxxxxxxxxxxxxxx https://www.pupman.com/mailman/listinfo/tesla
