PC electronics appears most often to be a POS
By comparison with any decent not-consumer electronic device, that is. I was spoiled by looking at the too-fancy switcher in the Otrona.. then I looked inside the Osborne1 (and even the later Zorba). Ugh.
I guess PC Power & Cooling remains the engineered choice for PSs, but are there any really Premium mbs out there? Ditto cases with industrial switches and decent jacks? I'd think any bizness would pay a little extra for quality in those areas. Wait!.. no, I guess I wouldn't bet that.
Hey.. Otrona - had some PS mon leds for *each* PS with go no-go levels for green/red. You could peek in from case vents to see if the "summary for all" led was a nice green. I thought... (that being CP/M days) surely ALL later \ufffd-stuff would at least: make that kind of troubleshooting EZ.
Hah.. maybe the country that Deserves Billy, deserves equivalent-grade hdwre too.
What did you mean re the mod. mb "450ish"? Be that the COST of that sucker!? And how odd that new, good qual caps would fail soon - vastly too much ripple-current for the actual cap rating? If so, you'd not likely have room! for any rated higher (if there are any that can handle massive ripple current). Heh: water-cooled caps - add to list!
'Least on Tek, seems that the -8 V ps is often a canary - hi ripple in any of several totem-poled other supplies seems to knock it way off.
Shee-it I Hate working on Junque. Especially crap knowingly designed to fail soon for MBA marketing designs. We seem started down the other side of the QC curve now: having found out how to do Five-Nines reliability - the scum in marketing are designing for sabotage, but please to call it [some lie].
