Care Guide
This is a large transmitting tube, model P250A, manufactured by JRC (Japan Radio Company), found during a clean-out of my family home.
My late father was involved in telecommunications-related work as a subcontractor for the former NTT (Nippon Telegraph and Telephone Public Corporation). I believe he acquired and kept this item through his work.
[Specifications and Condition]
• Manufacturer: JRC (Japan Radio Company)
• Model Number: P250A
• Size: Approximately 23cm in height, 13cm in diameter (approximate measurements)
A handwritten tape was attached with the words For Antarctic Communication. This is likely for a large-scale transmission facility used for communicating with the Antarctic observation team from Japan, or a selected unit for such a purpose.
• Condition: Visually, there are no cracks in the glass or internal damage. It is sold as-is, with no guarantee of operation.
Would this be of interest to those interested in communication equipment, or as a collectible or display item?

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.
Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
