John Brown 5160 power supply board
 |
The John Brown 5160 is an industrial‑grade AC‑DC power supply used in legacy IBM XT computers and similar equipment. Known failure modes include low or unstable 12 V/5 V outputs caused by degraded rectifier diodes, electrolytic capacitor failures on the output filtering stages, or defective switching transistors; overheating of the internal heatsink can also trigger thermal shutdowns. First‑check diagnostics: verify mains input voltage and isolation from the main power switch, measure output rails under no load for correct voltage levels, and visually inspect the board for bulging capacitors, cracked solder joints, or burn marks on key components.[oss-gpt-20b] |
