The 2050A designation identifies it as a xenon-filled four-electrode thyratron used for high-voltage switching in pulse-power and control circuits; some catalogs cross-reference this family with 0C3A and 03A designations, reflecting interchangeability in legacy power and regulation gear. The 0C3A reference links to the 0C3 family of gas-regulator tubes (VR105), a 105-volt regulator type typically employed as precise voltage references in industrial circuits. The tube’s physical envelope measures about 28 mm in diameter and around 62 mm tall excluding the IO base pins, and the device dates to around 1948, per museum records. In practical terms, this tube would have been used in equipment requiring robust, high-voltage switching or regulation capabilities, fitted in equipment with octal-based tube sockets, consistent with cross references to HB3\/RCA and GE designs. This combination of designations makes the tube familiar to enthusiasts and collectors who encounter RCA and GE catalogs from the era, as well as modern surplus suppliers who list the 2050A alongside 0C3A variants. This part is of interest to vintage tube restorers, collectors, or engineers seeking period-correct components for high-voltage control and regulation applications in restoration projects.\u003c\/p\u003e\u003c\/div\u003e","brand":"RCA","offers":[{"title":"New","offer_id":46285505659114,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-024.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/industrial-2050a-0c3a-03a-electron-vacuum-tube","provider":"GTG Hardware","version":"1.0","type":"link"}
