 Electronic components are suspended between these turrets and soldered to them to create a complete circuit layout.Most of the military electronics used in WWII made use of this construction method, and Altec professional gear of similar vintage has the same construction.However, the underside of some turret boards, such as a consumer Zenith 1A10 console radio, circa 1940, consists of an array of electronics components that are simply suspended, rather than tethered or soldered down, and thus could move unexpectedly.
