Hey guys so Im not sure why this wont work.. what am I missing? Ferrite core, 30 gauge about 100turns with 10 turns of 24 gauge. Powering with 120v A/C (U.S.A.) transformed to 19.8v A/C 60Hz... I have nothing hooked up after this I am just trying to test output with DMM?I get no freq. Or voltage. Either way I hook this up... step up or down.???
