Summary: |
St. James Laboratories Inc. Brands: Oscillector, Two-Forty St. James Labs (Chicago, 1920s) emerged from founder Robert St. James' passion for radio. Before WWI, he ran an amateur station and trained thousands in radio at Harvard during the war. Leveraging this expertise, he established St. James Labs, known for its superheterodyne designs, particularly unique glass-enclosed IF transformers. These boasted air core windings, dehydration for consistent performance, and matched pairs for optimal function. The first style (pre-1925) had green/white coils in a red glass envelope. The "Two-Forty" (late 1926) improved on this with lower resistance windings, simpler operation, and 240 kilocycle operation. Beyond transformers, the company offered the St. James Oscillector Unit and R.F. Choke Coil. Though not a household name today, St. James Labs' innovative designs, especially the vacuum-sealed transformers, played a role in shaping early radio technology. |
