Vintage 1969 Kolotron old tube radio with original box, diode, untested

AFW - Antique France Worldwide

Description

This lot includes a vintage Kolotron brand electronic tube, identified as a "Temperature Limited Diode," presented in its original box. 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.

The 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.

The 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.

This 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.
