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.

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

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.
