About Sanyo Semiconductor (a member company of ON Semiconductor)
Sanyo Semiconductor Co., Ltd. (a member company of ON Semiconductor) is a semiconductor manufacturing company with excellent power device technology, such as small packaging technology, high-efficiency switching technology, high-density packaging technology, etc., as well as the world’s YI flow simulation technology. Several analog-related assets include a wide range of process technology, analog design technology, skilled analog engineers, and specially designed and manufactured excellent energy-saving and environmentally-friendly devices, such as hybrid integrated circuits for inverters. Sanyo Semiconductor’s core devices include discrete circuits, general-purpose analog large-scale integrated circuits, ASSPs and hybrid integrated circuits, which are widely used in various products, such as personal computers, printers, cable TV, mobile phones, audio-visual equipment, game equipment, car audio System and air conditioning, etc.
Sanyo STK is commonly known as Sanyo Thick Film. Under the control of the tuned sound and high-precision semiconductor production process, it is not a level that ordinary amateur DIY players can reach. In addition to the better sound field and resolution, the low frequency is much stronger, which is completely the difference between professional athletes and ordinary players! These thick film circuits have always been customized products specially for big brand audio manufacturers. Many famous factories in the early days used them to manufacture power amplifiers, such as K+H, Sony SONY, Panasonic PANSONIC, Kenwood KENWOOD, JVC, Sansui, Sharp SHARP, Pioneer PIONEER, Aiwa AIWA, etc. Almost all Japanese audio It is selected by the manufacturer and has been used for more than 20 years. It has affected a whole generation, and it is also the sound that we heard when we were young with a strong brand of the times. Every time it sounds unforgettable. Sanyo’s company specializing in the production of power amplifier modules was later acquired by ON Semiconductor. After the acquisition, it integrated Sanyo’s traditional craftsmanship, coupled with ON’s unique design, and the later products are more brilliant, and are still used by major American companies. , Such as BOSE, such as Genelec in Europe!
Fortunately, I came across the new stock SANYO STK4174MK2 chip in batches. This model is an improved version of the STK41X1 classic series. It is a relatively early product. The design at that time was relatively conservative, the materials used were real and the tuning was strict. The designed output power is 40W+40W @8 ohms, and the distortion degree is THD 0.4%. It is not the extreme parameters that can represent good sound, just as many people still like the sound of tube amplifiers. The parameter performance is not necessarily high, but the sound is mellow and delicate like an old wine, the more it tastes, the more it tastes, so this time I chose a more classic retro shape design, regardless of the sound and appearance, the original look. This machine uses the Japanese second-hand disassembled E cow, which has a good performance in the middle and high frequency, and strives to reproduce the sound that once touched the soul. These second-hand disassembled cattle are exquisite in craftsmanship and the materials used are real. In the past few years, we have only collected about a hundred. This machine can achieve satisfactory results by pushing ordinary bookshelves or floor-standing speakers.
