It consists of two LM3886 amplifier circuits and is paired with a passive tone preamplifier, resulting in outstanding sound quality. LM3886 is a classic amplifier chip, known for its sound quality that directly rivals high-end amplifiers. The design materials of this machine are solid, the appearance design is beautiful, and the price is quite affordable.\u003cbr\u003e- The LM386 chassis is finely crafted, with a strong sense of design and high-end quality, and the internal materials are not ambiguous. The transformer is a 200W pure copper high-grade transformer, made of truly oxygen free copper wire and wound with a high-grade iron core, with excellent quality. The main filter capacitor uses two 10000UF capacitors for NOVER with sufficient capacity and strong sound. The main potentiometer in the input part uses for ALPS 27 potentiometer, and the operational amplifier uses JRC5532. Two single operational amplifiers, such as OPA627, can also be installed on the empty operational amplifier socket next to it to enhance the electronic tube odor, but the 5532 needs to be removed. Either install a dual op amp or two single op amps, both reserved for audiophiles to adjust and upgrade later. Coupling capacitors are two large thin film capacitors, which have much better performance than ordinary electrolytic capacitors, better sound details, and lower distortion. This low-cost material, combined with passive tone design, results in very low distortion, achieving a high-end level of both charm and quality.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eUsing Instruction:\u003c\/b\u003e\u003cbr\u003e- The LM386 output can only be connected to passive speakers and cannot be connected to active speakers or constant voltage speakers.\u003cbr\u003e- LM386 uses AC 220V mains power.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eSpecification:\u003c\/b\u003e\u003cbr\u003e- Model: LM386\u003cbr\u003e- Input method: RCA\u003cbr\u003e- Power amplifier chip: LM3886 x 2\u003cbr\u003e- Operational amplifier chip: JRC5532 x 1\u003cbr\u003e- Frequency response range: 20 - 20K at 1kHz±0.3dB\u003cbr\u003e- THD+N: 0.02%\u003cbr\u003e- Output power: 68W x 2\/4 ohm\u003cbr\u003e- Protection mechanism: speaker protection, boot delay\u003cbr\u003e- Net weight: 5.4kg\u003cbr\u003e- Product size: 335 x 220 x 80mm\u003cbr\u003e- Power supply: AC220V\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Included:\u003c\/b\u003e\u003cbr\u003e- 1 x Power Amplifier\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 750px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102074\/102074-01.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 750px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102074\/102074-02.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 750px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102074\/102074-03.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 750px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102074\/102074-04.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 750px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102074\/102074-05.jpg\"\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products, Audio Amplifer and Decoders","offers":[{"title":"Default Title","offer_id":41029049385009,"sku":"102074","price":231.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0578\/4790\/6353\/files\/1779067121-1.jpg?v=1780385338","url":"https:\/\/www.thanksbuyer.com\/de\/products\/lm386-68wx2-high-power-tone-power-amplifier-hifi-audio-amplifier-support-treble-and-bass-adjustment-220v","provider":"Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products,  Audio Amplifer and Decoders","version":"1.0","type":"link"}
