Fortunately, I encountered a batch of brand new stock Sanyo SANYO power amplifier modules produced in various periods, commonly known as Sanyo Thick Film. Under the control of the adjusted sound and high-precision semiconductor process production process, it is not a level that ordinary amateur DIY players can achieve. This machine is simply compared with the same power LM1875, and it is found that it is far better in all aspects than the LM1875 produced by players at all times, even the wave pattern most respected by players. In addition to better sound field and resolution, the low-frequency strength is much stronger, which is completely the difference between professional athletes and ordinary players These thick-film circuits are always customized products for large-scale audio manufacturers. Many famous factories in the early days used them to make power amplifiers, such as K + H, Sony SONY, Panasonic PANSONIC, Kenwood KENWOOD, JV JVC, Shanshui SANSUI, Sharp SHARP, Pioneer PIONEER, Aiwa AIWA, etc. almost all Japanese audio It has been selected by manufacturers and has been in use for more than two decades. It has influenced a whole generation, and it is also the sound of the strong brand of the times that we have heard for a whole generation when we were young. It is unforgettable every time it sounds. Sanyo&x27;s company specializing in the production of power amplifier modules was later acquired by ON Semiconductor of the United States. After the acquisition, Sanyo&x27;s traditional technology was integrated, and the unique design of ON, the later products are more outstanding, and they are still used by large American companies , Such as BOSE, such as the European Genelec
