Care Guide
These are vacuum tubes that were used in old 3-point separate stereos.
30MP27 x4 (one was damaged with a crack when removed; the top turned white, so I believe the vacuum seal broke.) Also included are 12BE6, 12BA6, with faded printing, so the model is unknown.
Since their functionality is uncertain, they are being sold as junk.
The 30MP27 is a power amplification tube used in 3-point stereos and radios in the early Showa 40s (mid-1960s). It could produce 4W of output with a low supply voltage and holds fond memories for hobbyists.

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.
