Calling all Old Timers. If you did the Heathkit Basic Radio course (EK-2A and EK-2B) in the late 1950s or early 1960s you may still have a coil that I am looking for. It is the "regenerative detector coil" part #40-303 and is used for numerous "experiments" in about three-quarters of the two-unit course. It is then removed from the chassis and never used again, which is why it is now very difficult to find. Perhaps you still have it at the bottom of a drawer? Do let me know and many thanks. Here is a full description -- click on the picture to get a nice big, clear document.
