Anyone have a complete list of capacitors for replacement in a //c plus power supply? Thanks!

Re: //c plus capacitor list

If you are talking about the internal voltage converter in the original IIc products, I was looking for this myself recently too. While I have found (and applied) some different fixes I've found for both IIe and IIgs power supplies, I've not had much luck finding information on the IIc internal units where others have successfully repaired these bad boys.

I usually target my repairs to the commonly failed capacitors, since I'm generally interested in getting something going quickly and save the full recap jobs for stuff I plan to keep around for a while. For this project, finding no information out there for a minimal repair, I just ordered up all the parts from Digikey the other day to at least go through and replace all the electrolytic caps. I just received them today and will start the project later this week. If it works out I can post back my results. Here's what I've recorded from the board myself and ordered up. The only difference is I think I ordered a 16v cap for C16, instead of the 10v one that is on the board.

Take this list for what it's worth, a basis for my initial experimental repair !!! If I get my board going I'll post my Digikey parts list to make it easier for others (oh wait, I ordered these parts from Mouser because Digikey customer service pulled a fast one on me recently, but you get the idea Smile

Whoops, I just noticed you specifically said //c plus. My list is useless for you. Sorry ...

Re: //c plus capacitor list

Although not for //c plus, that is still really great info - thanks for that! I'm definitely putting this in the reference folder because I think it will come in handy for later project(s). By all means post your results, but probably better to create new thread Smile
