    Can't make out the part number on the outside. But you may or may not be able to use that to find whether an individual capacitor is tantalum, niobium or aluminum

    in the Usa you use ounces and pounds, dont you?
    so its like 0,8 ounce of palladium per a pound

    The "metal" from these old russian brown capacitors turns to white when it's on air ( it coats with a white coating ) what could it be? silver-mica?
