Someone may have already produced one that has lower leakage, but you won't get near-zero leakage, which is due to capacitance between the winding and the core, unless you can get one with the core not grounded. You can reduce the leakage with a grounded core by increasing the thickness of insulation between the winding and the core. Not difficult. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk After swimming across the Hellespont, I felt like a Hero.
