Hi FMs

This is a PCB from a bluetooth sing along karaoke mic.

It stopped working suddenly so I opened it up and found this transistor blown. Now the markings on it are not completely readable. Only first letter as A and last letter as B.

I looked it up for schematics but could not find any. So by normal googling for it, I found it could be either A2SHB or A1SHB transistor.

I really want to fix it up. Can you guys guide me which one to choose and from where to source it ?

Thanks...

Hi

To be honest...most of these mics are made in china (local brands) and hence getting details will be a challenge......
