The tube, of classic cylindrical shape, is protected by a transparent glass envelope, revealing the internal filament structure and the various metal connectors at the base. The tube's black base bears a clearly legible handwritten label indicating the date \"27 MAY 1969,\" which precisely dates the period of use of this component.\u003c\/p\u003e\n\n\u003cp\u003eThe original box, made of rigid cardboard, features a retro graphic design typical of the 1960s, combining orange, black, and grey colours, as well as the diamond-shaped Kolotron logo. The inscription \"Temperature Limited Diode\" is clearly printed on the front of the packaging. The top opening of the box is visible, with a slightly folded flap, suggesting careful handling or prolonged storage.\u003c\/p\u003e\n\n\u003cp\u003eThe diode tube is distinguished by its multiple metal pins, all well-aligned and visually intact, suitable for mounting on vintage electronic supports. No major defects, chips, or cracks are visible on the glass part, which is remarkable for a component of this era. The whole presents an authentic patina, with slight traces of use or storage on the cardboard, without any apparent tearing.\u003c\/p\u003e\n\n\u003cp\u003eThis type of tube was commonly used in radio, audio, or electronic instrumentation equipment from the mid-20th century. The presence of the original box, combined with the precise handwritten date, gives this object additional documentary and historical value for identifying or restoring old devices.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eCondition\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eUsed item, sold as is, untested.
