{"product_id":"sylvania-6av5ga-vacuum-tube","title":"Sylvania 6AV5GA Vacuum Tube","description":"\u003cdiv\u003e\u003cp\u003eSylvania 6AV5GA Vacuum Tube is a beam power pentode designed for use as a line time base output valve in late-1950s television circuitry. The glass envelope measures about 36 mm in diameter and, excluding the base pins, is roughly 79 mm tall, reflecting its compact IO-base form factor used in tight chassis. This valve is intended for series heater chain operation in television sets and lists a heater current around 1.2 A, which informs how it is powered within a tube-string supply. As a beam pentode, it serves as a relatively high-gain timing\/amp stage in line-time-base circuits, supporting horizontal timing, sync, and raster generation in vintage CRT gear. The 6AV5GA belongs to a family of AV5GA tubes from the era, with related variants such as 12AV5-GA and 25AV5-GA designed for different heater voltages, illustrating how manufacturers adapted the same internal structure for multiple power-supply configurations. Sylvania (GTE\/Sylvania) produced these tubes for use in American television equipment in the mid-to-late 1950s, and today they remain sought after by restorers of classic CRT hardware.\u003c\/p\u003e\u003c\/div\u003e","brand":"SYLVANIA","offers":[{"title":"New","offer_id":46253359202538,"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-010.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/sylvania-6av5ga-vacuum-tube","provider":"GTG Hardware","version":"1.0","type":"link"}
