An American brand through and through, it was owned by AT\u0026amp;T until it was bought and revived in 1996 by entrepreneur Charles G. Whitener of Westrex Corporation. The goal was to manufacture vacuum tubes and high-fidelity audio equipment.\u003c\/p\u003e\n\u003cp\u003eIn 1997, a newly created run of Western Electric 300B tubes began shipping worldwide, to great excitement among the tube audio community. In 2017, a modern tube manufacturing operation was set up in Rossville, Georgia with the goal of modernizing 300B manufacturing, adding additional tube lines, and house research and design of new products under this proud revival of an original American brand.\u003c\/p\u003e\n\u003ch3\u003eCharacteristics\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eEf, Eb, Ec:\u003c\/strong\u003e 5 V AC, 300V, -61 V\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePlate Current:\u003c\/strong\u003e 60 milliamp\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAmplification Factor:\u003c\/strong\u003e 3.85\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlate Resistance:\u003c\/strong\u003e 700 Ohm\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGrid to Plate Transconductance:\u003c\/strong\u003e 5500 micromhos\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eMaximum Plate Voltage:\u003c\/strong\u003e 450 V\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMaximum Plate Dissipation:\u003c\/strong\u003e 40 W\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMaximum Plate Current for Average Tube (Fixed grid bias, Adjustable bias):\u003c\/strong\u003e 70 milliamp, 100 milliamp\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Western Electric","offers":[{"title":"Matched Pair","offer_id":41952541737144,"sku":"WE-300B-2","price":1499.0,"currency_code":"USD","in_stock":true},{"title":"Matched Quad","offer_id":41952541769912,"sku":"WE-300B-4","price":3099.0,"currency_code":"USD","in_stock":true},{"title":"Single Tube","offer_id":41952541704376,"sku":"WE-300B-1","price":699.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1564\/1247\/products\/WEbox.jpg?v=1741630539","url":"https:\/\/upscaleaudio.pro\/products\/western-electric-300b","provider":"Upscale Audio","version":"1.0","type":"link"}
