    Obviously...!

    Youngers I am sure do not know about AM demodulation through germanium diodes!

    Once, at the age of 10-11, I made the first AM radio with such a diode, and an old telephone earpiece that was connected to a vertical metal waterpipe. It was amazing experience to here the local radio station with this!!!

    I still should be having a couple of germanium transistors AC187 or similar in my toolkit from way back when I used to repair equipments.

    So, you guy seem to indicate that this part was used shortly after the invention of flint arrowheads but before flintlock rifles?
    My Creality Ender 3 S1 Plus is a giant paperweight that can't even be used as a boat anchor, cause I'd be fined for polluting our waterways with electronic devices.

    Not as dumb as yesterday, but stupider than tomorrow!
