Hi, my project is nearly on the right track https://www.badcaps.net/forum/showthread.php?t=115083 However, there's one last electrolytic cap that I need to replace and it's just not available, even at higher voltage. So, this question is a bit more general & maybe off-topic from my previous thread.
I'm recapping a powered speaker that contains a mains transformer & all e-caps are 105c-rated general-purpose radial cans. The one I can't match is 12000uF 50V 10mm-spaced snap-in, 30mm diameter, ±20% tolerance. And here are my options:
A) iffy quality: I've already bought some 63V JCCON off Amazon. I don't have the knowledge or gear to truly evaluate them. And even if they're ok now, how long will they work?
B) under-spec temp: digikey has in-stock quality caps that match in all respects, except they're 85c rated
C) under-spec capacitance: they also have quality 10000uF caps that match in all other respects [and they have 15000uF but 35mm diameter. won't fit on the board]
I'm leaning towards C, on the basis that 10000uF is within the 20% tolerance. And the amp worked for 15 years with Chinese TWBOR caps.
Which corner would you cut?
