The sound is full of classic amplifier flavor, mellow and durable, transparent, delicate, and silky. After listening to digital amplifiers for a long time, listening back to this classic circuit is a comfortable and comfortable experience for one ear.\u003cbr\u003e- All circuit boards use advanced components, for NOVER filter capacitors, red WIMA capacitors, Panasonic FC series fever capacitors, ROE small capacitors and NISSEI capacitors. Once obtained, it is in a HiFi state and does not require further refinement or optimization.\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePrecaution:\u003c\/b\u003e\u003cbr\u003e- The power supply of the circuit board requires the use of dual 28V high-power transformers, followed by the addition of a rectifier bridge to connect to the SF60 power amplifier board, and cannot be directly connected to transformers. Suggest using a 400W ring transformer to ensure effectiveness.\u003cbr\u003e- The AC15V interface of the circuit board is used to supply power to the protection circuit and requires a separate 15V output from the transformer. It cannot be shared with other circuits.\u003cbr\u003e- The static current of the power amplifier board does not need to be set too high, and the voltage measured at both ends of the output resistor is 15mV.\u003cbr\u003e- The installation and debugging of SF60 require professional circuit knowledge. If you lack experience, please study and understand before starting.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eSpecification:\u003c\/b\u003e\u003cbr\u003e- Model: SF60\u003cbr\u003e- Output channel: 2.0 channel\u003cbr\u003e- Power amplifier transistor: for SANKEN C3284\/A1303x2\u003cbr\u003e- Amplification: 28X\u003cbr\u003e- Frequency range: 20Hz - 20kHz\u003cbr\u003e- Main voltage: dual AC28V, with rectifier, single AC15V\u003cbr\u003e- Output power: 60W + 60W\/8ohms\u003cbr\u003e- THD+N: 0.005%\u003cbr\u003e- Protection mechanism: over-current protection, mid-voltage protection, power-on delay protection\u003cbr\u003e- Product size: 230 x 84 x 49mm\u003cbr\u003e- Net weight: 300g\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Included:\u003c\/b\u003e\u003cbr\u003e- 1 x Power Amplifier Board\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 800px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/98033\/98033-01.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 800px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/98033\/98033-02.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 800px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/98033\/98033-03.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 800px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/98033\/98033-04.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 800px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/98033\/98033-05.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 800px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/98033\/98033-06.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":41019766702129,"sku":"98033","price":77.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0578\/4790\/6353\/files\/1755048136-1.jpg?v=1780024204","url":"https:\/\/www.thanksbuyer.com\/cs\/products\/sf60-hifi-high-power-dual-channel-class-ab-power-amplifier-board-ultra-lm3886-tda7293-replacement-for-sugden","provider":"Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products,  Audio Amplifer and Decoders","version":"1.0","type":"link"}
