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 better sound field and resolution, the low-frequency power 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. In the early days, many famous factories used them to make power amplifiers, such as K+H, Sony SONY, Panasonic PANSONIC, Kenwood KENWOOD, JVC, Sansui, Sharp SHARP, Pioneer PIONEER, Aiwa AIWA, etc. Almost all Japanese speakers. 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 voice with a strong brand of the times that we heard when we were young. Every time it sounds unforgettable.

After the acquisition, Sanyo’s traditional craftsmanship has been integrated, coupled with ON’s unique design, the later products are even more brilliant, and they are still used by major American companies, such as BOSE and Genelec in Europe!
I was fortunate to encounter the early SANYO power amplifier module STK419-110 in batches of brand new stocks, which is a classic entry model of this series of power. Tuning, this module''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s field effect tube input amplifier circuit, the sound is warm and detailed, with unique flavor. The designed output power is 50W+50W @6 ohms, and the distortion degree is THD 0.2%. At that time, this thick film chip was only customized for the entire Japanese product, so it was difficult to see it on the market.
