Hello!

Sadly my sonos amp has stopped working more specifically the power circuit suppling 48v.

R1263 and R1262 resistors are blown, most likely that isn’t the only issue but it’s the only component in which i cannot read the value from. 

R1262 i’ve figured out has the value 102, 1kOhm

But R1263 i cannot find any information about. Does anyone know the Ohm value of that resistor?

I’ve marked the location of the resistors below. ( borrowed image )

From a very kind person i also got this from some of their old photos, but i can only read out the value of R1262 from it.

I maged to take a close up image of R1263 on my board, sadly i cannot make anything out from it.
