    I have a DeForest W05-41 Ch=10DA517 that uses a fixed capacitor and a variable inductor to select frequencies. As you can see the core/slug is broken and missing. Is there anywhere to purchase a core – not sure if it’s powdered iron or ferrite or what the difference is. Is there any work-around to get this going?

    Les;

    The easiest starting point that I could come up with is the core from the AM antenna in an older transistor radio. You could probably remove the adjusting screw assembly and see if it gives you any or all of the required range, by sliding it in or out.

    Thanks for the suggestions. I don’t have any older radios to use as sources, but I found a place that sells ferrite rods and slug rack cores – surplussales.com – in case anyone else is looking. I’ve orders a few to try so hopefully I can get this radio functioning.
