Overview
This is a rare, early 1930s RCA Victor condenser microphone capsule, model UZ-4083-B. It represents the pioneering era of electrical sound recording and early radio broadcasting, featuring the iconic early RCA 'meatball' logo on its original paper label. These rugged, heavy-metal units were the heart of the microphones that captured the voices of the Golden Age of Radio.
Story
In the early 1930s, Camden, New Jersey was the silicon valley of sound. This tiny capsule captured the voices of presidents, big band leaders, and radio pioneers, translating physical sound waves into electrical signals.
Maker / Origin
Formed by the merger of the Radio Corporation of America and the Victor Talking Machine Company in 1929, RCA Victor became an absolute powerhouse of audio innovation. Under the leadership of engineering geniuses like Harry F. Olson, they designed the microphones that defined the acoustic signature of the 20th century.
Condition & Value
The metal housing shows typical oxidation, dust, and surface wear consistent with age. The original paper label is remarkably intact and legible, though it shows yellowing, minor staining, and edge wear. The lack of testing means it is sold as-is, which keeps the valuation conservative.

Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.
Best Venue
