Product details:
STK350-23 high-power audio thick film integrated circuit is a product of Japan's
Sanyo Corporation. This series of thick film integrated circuits have
the advantages of high precision, flexible circuit design, good sound
effects, large output power, low distortion, stable performance, high
heat resistance and simple peripheral circuits. They are quite popular
in audio high power circuits.

1. Use original STK350-230, 2SA1943/2SC5200.
2. The inter-stage coupling capacitor adopts imported WIMA capacitor 2.2UF, with natural sound and wide sound field
3. The main circuit adopts five-ring metal film resistor with an accuracy
of ±1%, which ensures a good signal-to-noise ratio of the whole machine.
4.The PCB adopts a 1.6mm thick double-sided board and a 2.0 oz thick
copper spray tinning process to ensure good passing performance of large and small currents. First-class PCB quality.
5. The biggest feature of this board is the use of advanced speaker protection circuit, which
effectively eliminates the impact sound of turning on and off and the DC
output protection function, making your speakers safer.
6. The wiring layout of the whole circuit board is quite rigorous and
reasonable, and the whole PCB wiring adopts one-point grounding method.
The power amplifier board is stable and reliable, with high output
power; beautiful and round sound, and wide sound field. It has a strong
stereo effect, stable and powerful low frequency, excellent
signal-to-noise ratio, wide dynamic range; clear details, excellent
transient response, and can play all kinds of music with ease. It has a
very good performance in the home sound environment.
