Help to add voltage protection on cheap Chinese rhythm light circuit

[Willen]

Hi Willen,
Yes, I am an Indian. Good guess.

I am from Nepal and it's not hard to recognize a neighbour.

I find only similar chip on Aliexpress for music. This is similar PCB mounted and looks like it but have diff. IC number.
F.Y.I. - "https://id.aliexpress.com/store/pro...switch-the-music-chip/1036514_2001488041.html"
Wish I can find 803 IC. Really interested in fixing the light I have.
Thanks, SM.

Yes, the chip 803 looks like almost as as you found but little longer. You are in a expensive part of the world but VERY accessible part of the world too! Good luck Saurabh!
