Since the #Amiga 500 power supply was missing in the box, I ordered this RetroPower PSU:

It's pricey, but I thought I could share it with the VIC 20, Plus 4 and #C64 which I'm currently repairing. Unfortunately it's not possible: the Amiga model lacks the 9VAC output needed by the 8-bit machines
Why don't they sell a generic model with all the voltages, so you can simply swap the cable??
