Here’s to positive
+signs!
Still trying to clear the decks here so that I may return to my efforts concerning my second, attempted (so far, failed), PSU and order the additional capacitors for several more. I used 12.5mm United Chemi-Con caps to replace the original TEAPO 10mm caps found at C10 and C21. A bit larger, but my personal choice to replace the TEAPOs. Sorry for any concern, but you did warrant an investigation/re-visit here. Thanks.
I still intend to investigate/replace C30, 32 & 45 on my thus-far-failed, second AcBel attempt that seems to perform much like your current project/state.
Have finally opened up a Samsung PSU (from the “Omaha 5”), and
quickly closed it right back up after blowing it out. Andy has stated that “about 1 out of 50 of the Samsungs, violently self-destructs for no apparent reason”. Yet another reason for a “no thank you Samsung”. I’ll send Samsungs to Andy. Too jam-packed and otherwise possibly problematic for my taste. AcBels seem much mo’ bettah.
Even the smaller Quicksilver AcBel PSUs are fairly jam-packed (I recently discovered). And, not unlike the still-working MDD 400W AcBel here… this QS PSU also had some swollen and puffed caps… yet it still functions. Only after complete reassembly of the machine did I notice the PSU fan not working!
Fan did seem rather stiff while open/accessible during cleaning, but of course I did not test its function. It “tries” to turn with a little assist “push” through the case and I’d really appreciate
specific point-of-oil application insight/methods, just to determine salvageability and
IF the fan-circuit functions before simply buying a new fan… only to find that I need to investigate/re-cap the fan control circuitry. I was more focused on the little CPU fan and the processor thermal paste in this 1GHz DP QS, as the heatsink seemed overly HOT with very little run-time demand placed upon it.
Hopefully, a return to these matters in a week or two. Solid congrats on your efforts thus far. Wonder if anyone else here has ventured into their “dormant” PSUs?
