I am repairing a Delta DPS-250AP-8 power supply from a Fujitsu SFF machine. The main fuse was blown, and culprit was that one MOSFET is shorted. Standby +5V line came up nicely when I powered it via a variac.
I ordered the MOSFET, but there are still two burned looking resistors. One is too charred, but the other looks reasonable. However, upon further look I can't get proper value off the color rings, as the colors just don't add up.
Colors are: red, red, silver, gold, silver.
0.22 ohms perhaps?
Or if perhaps someone has the proper schematics, these two are labeled R8A and R8B.
See the attached pictures. Thanks!
