Power Supply drop at 120vac in
This machine runs fine with 122-123volts AC in.
With normal 120volts AC, internal and external USB-powered HDD's fail.
I assume the power supply is failing.
What is the experience with this? A particular capacitor or caps (as in G5's) or other component?
Or should I just replace the PSU?
Hi Mayer, to clarify: At 120vac the internal HDD fails, and the external, USB3 HDD backup fails as well.
Additional info: About a year ago, after 2 years of service, at 120vac, the external HDD failed. I suspected voltage drop across the connectors joining a 2M USB extension cable to the short USB2/USB3 cable shipped with the HDD. I replaced the 2-part cable with a single 2m USB2/USB3 cable and all was well for a year. I did not measure voltages at that time.
So evidently power drop has progressed since then.
BTW, I also got my Apple II in '79. Quickly got another one for my office. Interfaced it with my Telex machine. Then got my secretary into word processing on it.
Is this a good question?
