Hello everyone, I was on this list about 20 years ago (wow does time fly)! I'm doing a big rebuild and getting my coil back together now. My question is about using a variac as a line filter? Will that iron core attenuate RFI better than a commercial line filter? ~Dan Kansas City area _______________________________________________ Tesla mailing list Tesla@xxxxxxxxxxxxxxxxxx https://www.pupman.com/mailman/listinfo/tesla
