The circuit uses direct coupling and has a good low-frequency response; the input stage uses differential amplification with low noise; the output stage uses a Darlington composite tube, which has high gain, high power, and low distortion. This circuit is especially suitable for making home power amplifiers and power amplifier circuits for active speakers, and the effect is very good.\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/div\u003e\n\n \u003cdiv\u003e\u003cspan style=\"font-size:18px\"\u003e\u003cspan style=\"font-family:arial, helvetica, sans-serif\"\u003eThe OCL high-power amplifier kit is dual-channel, and the two-channel circuit principle is exactly the same. Take the right channel (R) as an example. In the circuit, Q1 and Q3 are the differential amplifier input stages, Q5 is the driver stage, and Q7 and Q11 constitute a complementary composite output stage. The output signal is taken from the emitter of Q11 and the collector of Q13. The output audio signal can directly drive the loudspeaker to emit a loud sound. This circuit also adds R25, R27, C11, and C13 to reduce static noise.\u003c\/span\u003e\u003c\/span\u003e\u003c\/div\u003e\n\n\u003cdiv\u003e \u003cspan style=\"font-size:18px\"\u003e\u003cspan style=\"font-family:arial, helvetica, sans-serif\"\u003eThe transformer in the store is a 12V 8W dual power transformer\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/div\u003e\n\n\u003cdiv\u003e \u003cspan style=\"font-size:18px\"\u003e\u003cspan style=\"font-family:arial, helvetica, sans-serif\"\u003ePower supply voltage: dual power supply AC12-18V\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/div\u003e\n\n \u003cdiv\u003e\u003cspan style=\"font-size:18px\"\u003e\u003cspan style=\"font-family:arial, helvetica, sans-serif\"\u003eOutput power: Po=20W+20W (RL=8Ω), 30W+30W (RL=4Ω)\u003c\/span\u003e\u003c\/span\u003e\u003c\/div\u003e\n\n\u003cdiv\u003e \u003cspan style=\"font-size:18px\"\u003e\u003cspan style=\"font-family:arial, helvetica, sans-serif\"\u003eLoad restriction: 4-8 ohms (8 ohms\/30-60W is recommended for speakers)\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/div\u003e\n\n\u003cdiv\u003e \u003cspan style=\"font-size:18px\"\u003e\u003cspan style=\"font-family:arial, helvetica, sans-serif\"\u003eOutput voltage: 4-8 Ω.\u003c\/span\u003e\u003c\/span\u003e \u003c\/div\u003e\n\n\u003cdiv\u003e\u003c\/div\u003e\n\n\u003cdiv\u003e\n\n\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H1c69a805878f4001a3a3d3dbd70bbad2s.png\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H015797525bd84d24a62a68581ce50487x.png\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H99f240efa19341d29523c6575690d89ba.png\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Hee8570be7c8f4371b53f895a6a2f3b12c.png\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H1216c709bc464b4dbd5b5532b9e20882A.png\" slate-data-type=\"image\"\u003e\n\n\u003c\/div\u003e\n\n\u003cdiv\u003e\u003c\/div\u003e\n\n\u003cdiv\u003e\n\n\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Hf4c678255a434f9baabf73b0d584e8aaN.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Hbe8976fa61dc486c90bdf0ca814b7f95T.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H2467f3d56f3b448896abe2a2ec2cc4e7E.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Headba9dce96d4a948487e9945eb91b9e4.jpg\" slate-data-type=\"image\"\u003e\n\n\u003c\/div\u003e\n\n\u003cdiv\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/HTB1ByqaaOzxK1Rjy1zkq6yHrVXa0.jpg\" slate-data-type=\"image\"\u003e\u003c\/div\u003e\n\n\n\u003c\/div\u003e\u003c\/div\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Finesse Room","offers":[{"title":"Default Title","offer_id":56377351373135,"sku":"\u003cnone\u003e","price":9.96,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0954\/0603\/1183\/files\/H0ba7e68842ef4058ab09de4492618b4fm.webp?v=1762781999","url":"https:\/\/www.mastegod.site\/en\/products\/electronic-diy-kits-ocl-amplifier-board-suite-ac-12-18v-100w-dual-channel-stereo-eletronica-electric-experiment-diy-electronic","provider":"Mastegod ","version":"1.0","type":"link"}
