Hi everyone!
So, i have this very nice powered speaker which is blowing fuses.
I replaced both MOSFET on the primary side of the PSU because they were basically dead shorts.
Now, it keeps blowing fuses, and i just noticed this little resistor in the switching control section looks a little bit too dark (r13).
I'm not familiar with SMD, so i'm asking here to make sure i order the right part. (UPS already came twice for this repair).
It's hard to read but i think i can read "180" on the resistor, so could be 18 Ohms?
What is that size? my bad calipers tell me something like 3mm x 2.54mm. My guess would be 1210?
Any opinion on that?
Do you think another component might have gone too?
Thanks!
Thomas
