    Lightbulb Soviet USSR KT Transistors - Scrap Gold

    KT Transistors have quite a bit of gold in them, however they are very poorly documented in the scrapping world outside of the former Soviet Union.
    What you are looking for are 3 legged pnp transistors usually with the markings "KT" and a 3 slotted hole in the top middle. They were used in many Soviet produced items.
    .

    .
    The gold plated parts inside of the transistor are about 1 in 30 gold by weight.
    .
    Some of the part numbers are:
    .
    0347 KSB7720 ( KSV7720 )
    0347 KSB772R ( KSV772R )

    T7 683B ( 683V )
    V4 626B ( 626V )

    ( I did not include the 'bell' shaped transistor numbers - they also have gold in them )
    ( Please post if you have more KT numbers for this specific type of soviet transistor )
