Thank you very much, these Panasonic waters from the warehouse of an electronics company in the country I live in. My Esr meter is broken, I couldn't measure it. When I measure with the meter in capacitor mode, they have values between 205 225uf. No visible leaks for now.
Bought just an hour ago for 1 buck from a scrapeyard.Most caps are Panasonic SU, some are Panasonic " Pureism" whatever that means, some ste panasonic HFZ...I could bet tHE Pureism and SU csps have identical manufacturing process just bu the looks and size.
Let's not forget that in the 70's John Curl and Mati Ottala both signed a document telling that capacitors are bad for coupling audio signals ... Right or wrong...that ment that capacitor manufacturers had to rebrand all their usual capacitors "for audio" even if it was about mains filtering capacitors ...Thus a myth was born to fight another myth as Mohamed was invented to fight Jesus....
Simple truth is there's no special capacitor for audio and no amplifier better just because it's not using capacitors.There's not a single audio amplifier on Earth that doesn't make use of a single non audio capacitor.

The funny thing is that these two boards come probably fom a a blue ray player having a pretty complex active filter with some green film foil caps marked Audio, lots of small black bipolar caps marked Pureism on one side of the pcb and 5 x njm4558 on the other 🙂

green film foil covers look very good.. They are exactly the material I was looking for, made in Japan.
I have both bipolar Panasonic and bipolar nichicon muse 10uF/50V.The panasonic cap is about 8 times bigger than nichicon muse, its electrolite+ paper is visibly wet and cleatly heavier, while nichicon muse paper + electrolite looks almost dry.
They both measured fantastic in independent tests by Cyril Bateman and Neurochrome although they clearly use very different technologies.They might just have very different lifetime if stressed under heat.I have them both and I only preffer the Muse over the Panasonic when size matters or i just don't have enough nichicon caps.

Next time try opa2132 or opa132 instead of the Bursons.You'll thank me later.
I can't get samples from anybody.I wouldn't use Bursons even if I get them for free.I only need more opa2132 🙂
The 33u/16v bipolar muse and the same values bipolar pureism panasonic caps are identical in size. Same are 100uF /16 Bipolar SU panasonic and 100uf /16v nichicon muse . The 10u/50Panasonic bp ce is definitely 2...3 times biger than the 10u/50 bp muse on the pcb.Not 8 times though...

I too enjoyed the OPA2132 over the Bursons in my WHAMMY. I actually ended up with a pair of OPA828 as my favorite.
You need a pair of medical grade Triads? I've got a couple for sale. 😉
