Turret boards consist of a thin (generally 1/8 inch) piece of insulating material drilled in pattern to match the electronic layout of a set of components.Electronic components are suspended between these turrets and soldered to them to create a complete circuit layout.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.Popular DIY components utilizing this approach include reproduction vintage guitar amplifiers and certain professional studio components from the 1960s, such as the classic and still widely used Teletronix LA2A tube compressor.In general, however, due to the expense and time-consuming nature of turret board construction methods, experimental or test-stage electronics projects generally make use of one of the many types of perfboard available, while final circuits—both hobby and commercial—use printed circuit boards.
