So I opened ip my caps box and took a few measurements on some caps I bought, before I got wiser.
There are 16v 1000uf 10mm, 16v 1000uf 8mm, 6.3v 1500uf (real & used), and 16v 2200uf.
The 16v 1000 10mm have no series identifier. Their ESR is .03, their capacitance is 1050. They are consistent from cap to cap. They have an elaborate bung with three projections. Their colour matches that of the used ones I have taken off motherboards. I think these are real.
The 16v 1000uf 8mm are .015 ESR, capacitance 980, consistent for the lot. Series is WG.
The 6.3v 1500s came off an Asus TUSLC-2 I recapped. I measure their ESR at .02 and their capacitance ar 2100 (yes). They are WX series.
The 16v 2200uf are a bit of a muddier green than the others. Their is a "wave" in the series lettering. ESR is .02 but the capcitance is 1550(!) and there are variances among
them. I believe these are fake.
All have the "K" on the top. Pictures were blurry so I did not post.
Do you see more fakes than the 2200s?

I've been working on a 1984 Sanyo 27" color TV which had a smattering of bad caps in the video switching circuit. I found this oddball little 1uF 25V cap which looks to me like an early polymer, but I can't find concrete info proving it. I know Sanyo was a big player in early polymer cap development and this is the time period where they were just getting on the market, so I'm wondering if anyone has crusty old datasheets that could help identify it and determine if my suspicions are right? It has the same epoxy end seal and font/formatting as some old stock Os-Cons I've got laying...
