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 the 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 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 audio systems. 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.

Fortunately, I came across a batch of newly stocked power amplifier modules STK404-120 later produced by Sanyo SANYO. There are many models in this series, including STK404-050-140. Among them, STK404-120 is the more powerful one. This series of products are produced in a later stage, using typical classic circuits, with relatively simple circuits and small packages. The sound is expressive. The designed output power is 80W+80W @6 ohms, and the distortion degree is THD 0.4%. Pushing general bookshelves or floor-standing speakers can achieve satisfactory results. At that time, this thick film chip was only supplied to manufacturers who made complete machines, so it was difficult to see them on the market.
This board is designed in accordance with the concept of fever. The materials are carefully selected. The power amplifier module can be installed flat or vertical. It is easier to achieve multi-channel function with a suitable radiator.(The filter capacitor of this board is a second-hand disassembled product, with a specification of 63V7000UF and a size of 35X35mm. There are not many filter capacitors of this size)
Sound performance: The overall tone is warmer, the sound is softer, the treble extension is higher but not harsh, the bass dive is deep enough and the elasticity is very good, not mixed or muddy. Sanyo thick film is a kind of circuit between integrated and discrete power amplifiers. The fine workmanship and excellent craftsmanship are better than 3886 and 7294, and it is difficult for ordinary DIY players to reach this level.
