TDA2616 replaces TDA2615 replaces TDA1521

Changhong 2966 sound TDA2616 can be directly replaced with TDA1521, disconnect the 2 feet of TDA2616 from the circuit board.
Weld the TDA1521, and connect pin 2 and pin 3 to be OK.

The last two channels of a Sansu C-28 type composite audio system are silent, and it is found that the power amplifier block TDA2615 of these two channels is damaged. Buying out of stock in many places. In this stereo, the first two channels use the TDA2616 power amplifier block. Through the real drawing circuit, compared with the TDA2615 power amplifier circuit, except that the two power amplifier blocks are slightly different in package form, the pin functions are completely the same. Try to order a TDA2616 from Guangzhou by mail, and the direct exchange is successful.
