- Here is another version I made using STK 403-070. The amplifier I built in this video is a simplification of the original classic circuit. Unmute and standby. Input, output and speaker delay circuits have been simplified.
Subscribing, liking and sharing are your greatest support for me, thank you.

Спасибо)
i want this full assemble board with out ic ,please help me
Porfavor tendras el diseño o diagrama para hacer la placa del amplificador? Gracias
Consulte los minutos 4:28 ~ 4:33 del vídeo.
Awesome project
Thank you for your compliment
Please reply if can I use STK 402 - 070s on this board
The pinout is different, so you can't use STK402 - 070s directly on this board
@@stelectronic645 so is there any board made for the IC STK 402 070s? Is there is one available online kindly give me the link
Sorry, I didn't find it
Puedes crear placa para STK412-150 por favor.
Lo siento, no tengo el chip STK412-150.
Hai This power amplifier board available if pls let me know the cost of the board and also with power board
The circuit board is homemade. Please see the video for how to make the circuit board: ua-cam.com/video/aemG_4sDz_Q/v-deo.html
Pcb layout plz
Please refer to this video 4: 25 ~ 4: 34.
Can I ask for a PCB layout?
Please refer to 4:28~4:33 of the video.
