This circuit is a voltage-dividing current negative feedback single-stage low-frequency small-signal amplifier. It uses RP, Rb1, Rb2, and fixed base potential (change the RP to adjust the static operating point) , Use the emitter resistance Re to obtain the current feedback signal, so that the base current changes accordingly, thereby stabilizing the static operating point.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eBoard size: 7*4.6cm\u003c\/p\u003e\u003cp\u003ePower supply voltage: DC 6-12V (prevent the LED to reach the brightness visible to the naked eye, the voltage should be 20-30V)\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePackage includes:\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e1 x DIY KIT\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"http:\/\/imgmgr.banggood.com\/images\/oaupload\/banggood\/images\/56\/4A\/5e160175-ad29-42d1-a182-bbff6b5999b7.jpg\" style=\"width: 800px;\"\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"http:\/\/imgmgr.banggood.com\/images\/oaupload\/banggood\/images\/3B\/AC\/02f69f1d-a7b1-4f51-a72b-587538194c15.jpg\" style=\"width:1000px\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"http:\/\/imgmgr.banggood.com\/images\/oaupload\/banggood\/images\/18\/19\/9d59c164-812d-463b-b710-2505485ef6d9.jpg\" style=\"width:1000px\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"http:\/\/imgmgr.banggood.com\/images\/oaupload\/banggood\/images\/E0\/76\/e823e9c3-68a8-4d26-85d6-3a775d82dda5.jpg\" style=\"width:1000px\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"http:\/\/imgmgr.banggood.com\/images\/oaupload\/banggood\/images\/86\/54\/4d805c1e-f36a-4b33-9077-0c47ac167175.jpg\" style=\"width:1000px\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"http:\/\/imgmgr.banggood.com\/images\/oaupload\/banggood\/images\/52\/0F\/9016dba5-60ee-4177-a77b-8cfa4c8c3a22.jpg\" style=\"width:1000px\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"http:\/\/imgmgr.banggood.com\/images\/oaupload\/banggood\/images\/61\/FE\/c7d36a07-e07d-4fdc-b94e-112cd10b6903.jpg\" style=\"width:1000px\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"http:\/\/imgmgr.banggood.com\/images\/oaupload\/banggood\/images\/57\/70\/d47fecbf-4d97-4222-93f0-136cecb65f58.jpg\" style=\"width:1000px\"\u003e\u003c\/p\u003e","brand":"Electronic Pro","offers":[{"title":"Default Title","offer_id":35368570552476,"sku":"1709443","price":210.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2787\/9162\/products\/3cf3dbe7-7ad0-4f92-bfed-84da467a226a.jpg?v=1596624844","url":"https:\/\/electronic-pro-south-africa.myshopify.com\/products\/single-tube-low-frequency-amplifier-circuit-kit-triode-common-fire-amplification-diy-welding-parts","provider":"Electronic Pro ","version":"1.0","type":"link"}
