Replacing the Capacitors in an Apple ][e Power Supply Unit.
While, yes, this subject has been raised here previously, I felt it was time for an update (the referenced site below was updated this month). Two days ago the "magic smoke" appeared above the power supply on an Apple ][e. Actually, it was only "semi-magic smoke" as the power supply unit (PSU) kept working. But I know enough to shut off and unplug smoking electronics immediately. Also, research reveals that the failures cascade to a worse condition if you keep using a PSU in this condition (damaging the mother board).
THE BIG STANDARD WARNING:The PSU is not a user serviceable part. Anything you see here is not to encourage you to service it yourself unless you are fully aware of the high voltage capacitance in these circuits that can electrocute you and kill you DEAD!!! DON"T DO IT unless you know what you're doing.
Having said that, I now bow to the combined knowledge here with the following question: If I have thoroughly disconnected the PSU, open mine up, wearing the thick rubber electrically insulated gloves, and discharge each and every capacitor manually, do I have to worry about any other charges? I also know that when the danger of leaked capacitor fluid, which is carcinogenic, needs to be completely cleaned up, etc.
Obviously I want to do a re-capping job on my PSU. I found a good, recently updated site with some good information, including a parts list, (though I note that the filtering capacitors information is not as detailed as Speedy has previously posted here on the AF board).
I plan to proceed with this if it's economically feasible. I know that ReactiveMicro will do the job for $90 per PSU. Is it worth it? Probably. But how much does it cost to do it myself? Is replacing the caps enough? Are other components robust forever, or are some others about to fail too? Is it better just to get the modern $40 PSU replacements? I'm not a purist, I don't have to keep the original equipment. But if fulfilling the parts list costs around $20, I'd definitely do the re-capping myself. I'm probably going to do about 10 of these PSU's, so a somewhat bulk purchase will save shipping costs.
