Customer brought in a PMP5000 with channel B blown.
Actually it blew gracefully.
The (3) mosfets are toast. The .03 ohm current sense resistor is a puff of carbon.
And T12 & T16 are shorted.
I am having a bit of a problem sourcing the 3 milliohm resistor because I do not know the wattage rating.
If the component length is any indication, I would have to say it is a 3 watt device.
I found this item at Newark:
VISHAY DALE|WSR3R0300FEK|RES, CURRENT SENSE, 0.03OHM, 3W | Newark.com
Does anyone know the actual wattage rating of the Behringer resistor?
