Profile Power Supply Blown Resistor
Posted by: MacinPosh on 2018-08-13 00:18:22
Inspecting the Profile power supply board, I noticed a very burnt resistor that had cracked into two pieces.

I'm having trouble identifying its value. Can anyone help me out? It looks like Brown-Grey-Orange-Grey-Brown?

Thanks

Can you use the schematic to identify the value?

Unfortunately I don't think that's the correct schematic for the board.

The component is from the small daughter board connected to the Astec Power Supply AA11770
