STK4241 STK4201 STK4221 STK4211 STK4231 Amplifier Circuit

| 2019/06/13

The amplifier uses a hybrid two-channel IC STK4241-II manufactured by SANYO. Immediately, it is worth noting that the pinout of the STK4241 is compatible with such chips as the STK4201V-series (THD = 0.08%) and the STK4141-series (THD = 0.02%). In the archive for download you will find 5 technical descriptions (DATASHEET) on STK4201, STK4211, STK4221,…

Stereo Amplifier Of 500 Watts Quasi Complementary
