New high-power thick film STK404-120 fever level mono amplifier board finished product

This board is designed according to a more enthusiastic concept, with all interfaces free of welding and non-destructive installation. The materials are carefully selected, and the power amplifier module can be installed horizontally or vertically. With a suitable radiator, it is easier to achieve multi-channel function.

(This board’s filter capacitor 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 timbre is warm, the sound is relatively soft, the high pitch has a high extension but is not harsh, the low pitch has a deep dive and good elasticity, and it is not mixed or messy. Sanyo thick film is a type of circuit that lies between integrated and discrete power amplifiers. Its exquisite craftsmanship and excellent craftsmanship are stronger than 3886 and 7294, and it is difficult for ordinary DIY players to reach this level.
