STK433-330/130 thick-film module hi-fi audiophile amplifier finished board – 150W+150W stereo

STK433-330 and STK433-130 are thick film power amplifier modules produced by Sanyo. They were originally used in Yamaha RX-V371 combined power amplifiers. They are 3-channel and 2-channel AB class modules respectively. The maximum output power can reach 150W@6 Ω. STK433-130 signal to noise ratio is as low as 0.01%, usually used for stereo. Sound shows good results,The medium and high frequency characteristics are good, the frequency response can reach 50KHz, the resolution is strong, the separation of human voice and musical instrument is excellent, and the low frequency is solid.

This product is a power amplifier board developed based on STK433-330 and STK433-130. The power amplifier board does not contain modules.No accessories included.Without heat dissipation,You need to buy modules and radiators separately to use, no debugging, plug and play.
