I’m trying to build the (Floyd Carter) capacitive discharge circuit, found in the 80’s RC Modeler magazine .Im wondering if I can use an e-core instead of the toroid core, for faster winding time.
Does any one know if this can be done? I'm trying to save money. Just got married!!!! BROKE.. I have salvaged some e-cores from a TV and VCR’s. No luck on finding any toroids yet. Any help would be greatly appreciated.
