Estupendo trabajo compañero.....¿habría posibilidad de facilitar el esquema eléctrico en Pdf?....Un gran abrazo fraternal desde Las Islas Canarias (España).......
This solution is also applicable to STK403-090/100/120/130. It should be noted that these chips have one more pin. Pin 1 is -pre vcc. Pin 2~pin 15 correspond to pin 1~pin 14 of STK403-070.
It is generally difficult to measure the quality of thick film integrated blocks with a multimeter. Damage to the power amplifier IC is usually caused by breakdown of the final push-pull transistor. You can use a multimeter to measure the resistance value between the output terminal and the power supply terminal to roughly determine whether it is damaged. If the resistance is found to be very small, it is basically broken.
Gracias por su atención No se puede reemplazar directamente. Aunque los dos circuitos son básicamente iguales, debido a que los pines del módulo amplificador de potencia son diferentes, deben ensamblarse de acuerdo con la definición de pines.

Thanks for watching. Sorry, I only have jpg, no pdf. You can get the circuit in the video.

Hi, the video turned out very cool! Could you please tell me if this scheme is suitable for stk403-100 and stk403-130?

@@stelectronic645 Thank you very much, this will help me in assembling on 403-100, 403-130, 404-130s
I have one such chip. But I don’t know if it’s working properly or not. How can I check its serviceability?

Super
Good
Thank you sir please can you please show me how to make mini amplifier nd circuit working on 4.2v or 12v thanks
Esse esquema pode valer com STK 433-070 ??
The circuit is basically the same, but cannot be directly replaced. Note two points: 1. The pin definitions are different. 2.433-070 has a -pre pin.
5:29 kindly send schematic diagram of amp.using STK433-070, Thanks.
hola buenas noches ,olle puedo utilisar el STK402-070N
Gracias por su atención

Power💪
Hi kindly send this ic circuit diagram
You can get the circuit diagram in the video at 5:30.
Spare part list pls
Spare parts list is at 00:32 in the video.
Sorry the display time is too short, thank you for your attention.

Здравствуйте можно ли подключить данную микросхему в мостовом включении?
Извините, я не проверял внутреннюю схему чипа, поэтому не могу быть уверен.
