Commodore Amiga 2000 Power Supply repair

I lost too much time to repair only one of two psu, not convenient. Better to replace only the PCB with a ATX power supply (only the PCB!)

Defect:

  • Dead.

Replaced components:

  • 2 x Diode IN4001
  • 1 x Diode Zener 5v1
  • 1 x Triac BTB 16 200B (recovered from another power supply)
  • 6 x Electrolytic Capacitors.
  • 1 x Power supply plug with a filter RIFA inside.

    can you use that cap meter to measure caps while are soldered on the board?
    thx

    Ha Ha,

    i´m repairing the same PSU.
    Short between Ground +12V and +5V.

    1 cap had a short
    1 cap out of specs
    and the BTB 16 200B is death.

    wish me luck that that’s all

    @ettore
    Unfortunately, no. I swapped all the capacitors. The ic swapped. Everything re-soldered. The diodes checked, etc. But the voltage fluctuates extremely with 5 and 12 V line.
