- Fixed Condenser, Used in the Hammond Radio Research Laboratory, circa 1911 - John Hays Hammond, Jr., was largely responsible for launching the field of radio control. In 1926, he built a medieval-inspired castle in Gloucester, Massachusetts. This site served as his home and research laboratory. With over 400 patents to his name, Hammond developed ideas for radio control, autopilot function, and targeted missile detonation. This device was used in Hammond's laboratory.

- Faradon Variable Mica Condenser, Model UC-1819, 1920-1925 - Early radios containing vacuum tubes needed both AC (alternating current) and DC (direct current) electrical power to operate. Condensers (also known as capacitors) allow alternating electrical currents to pass while blocking direct currents. Condensers can block, pass, filter and tune the various currents of the radio.

- Variable Condenser, Used by Alfred N. Goldsmith, 1920-1930 - Condensers (also known as capacitors) allow alternating electrical currents to pass while blocking direct currents. Condensers can block, pass, filter and tune the various currents of the radio. This device was likely used by Alfred Goldsmith for his experiments while he was the Research Director of Radio Corporation of America. Goldsmith aided in the development of the first commercial radio-phonograph.
