New Member with Philco 38-12 open oscillator coil
#9

    Hello Ernie, here is a picture/diagram I drew of the oscillator coil in my 38-12. I carefully unwound the secondary and got 1 continuous piece of wire with no breaks. It measured 1.5 ohms; this is why I believe the schematic is incorrect as it says 3.5 ohms. Maybe when the schematic was printed, someone put the wrong number in. Just a suggestion. The original wire measured 1.5 ohms so I rewound using 34 guage wire and it measures 1.6 ohms; almost like the original. Hope this picture helps.
