Guys! please! I really need a return here.
The power supply of my Creative A520 speaker system got nuked in lightning. I tried an external adapter 12V/1Amp and it works with occasional volume loss during heavy bass. I guess the adapter is unable to supply enough current.
I am trying to repair the power supply but cannot figure out the values of the burnt parts.
I can see two resistors and a zener diode as burnt:
Please help me figure it out.View attachment 94210
