- In the realm of audio electronics, the capacitors we choose can make a world of difference. With the discontinuation of the beloved Nichicon capacitors, the quest is on for the perfect replacement. In our latest exploration, we're pitting solid polymer capacitors against the classic Nichicon. While polymer capacitors boast superior ESR and ESL parameters, their steeper price tag-ranging from $1.5 to a whopping $5.5, compared to Nichicon's modest $0.45 to $0.75-might make audiophiles pause. Brought to you by renowned brands like Wurth Electronics and Kemet, let's delve into this clash of titans. Stay with us as we evaluate their performance and await the grand reveal in our upcoming sound comparison video. Let the capacitor combat begin!

Do these go in series with the output?
Personal opinion but Nichicon Muse caps look great on any circuit board, That color just makes component look HQ. Did you compare leakage current between all of these?
Maybe you should take a look at the Chemi Con KZH series data sheet. Chemi Con KZH 35V 390µF 8x20 mm 6000h @ 105°. If you have a device, you can also measure whether + or - DC is present at the electrolytic capacitor.
Hi, I got a weird question and was wondering if anyone could help me. I just bought a Japanese tape deck and I need to buy a converter. Doesn't matter which wattage I buy or does that matter? I'm confused to the whole thing. This is my first time buying one
Hi, Steel. You should be able to find a consumption on the back of the deck on the label. Most of the decks are around 30W. I would recommend to use 200-500W adapter. my favorite is www.amazon.com/gp/product/B07L56PYZS/
@@hifirulezzz thank you very much
What capacitors are those? Can you use them in amplifiers?
Please read a description for the video.
Not sure what country you are in but can you please recommend someone in the USA that can recap and service my decks? Thank you.
Well, I am in the PA, USA.
email is hifirulezzz@gmail.com
I am in PA too. This is great news for me because I have a bunch of decks I need servicing. I’ll email you. Thanks.
As a long-time electrical engineer, specializing in guitar pedals, I would have to say that the reds taste much better than the green ones. Now who are you people and where is my horse?
what's your reason picking polymer over metal film caps?. i see space is not a problem here
Metal film for 47 uF? I have not met that big.
@@hifirulezzz yes they do exists. i used some 47uF metal film caps though you're going to pay premium for it.... and they took quite some space too
@@n.shiina8798 $18 a piece and size of the fridge? are you sure?
@@hifirulezzz depends on the brand. if you're going to go with regular brand like Epcos, Vishay, etc then yes, around that much. size wise, maybe espresso cup as a scale?
Even Elna Duorex have been discontinued, I guess a long time ago. Some say they are PCB killers, but none of those in my K950 have failed.
It's 33 years on, unknown hours of operations and they still measure normal I believe. I am going to replace them at some point but.... with what? I'd be ashamed to install those half-sized caps, even worse aluminium bodied caps... oh no, I couldn't let that happen, not even if they sounded better than Duorexes.
You would not believe how well and linear these polymer caps are. Now my 555 performs like a Nakamichi, recording highs at -6db level. This was never happening before with any other caps. Stay tuned for the next videos.
It might depend on the capacity with the ELNAs, but it's a huge risk with them. We know that their electrolyte is simply unstable, so keeping them is like timebomb. In the Kenwood kx-5010/9010 decks, they've used silmic's, and while the smaller values are generally fine when it comes to measuring them, the 470uF ones have leaked. I've even seen an instance that these have even killed the regulators. I would recommend replacing ANY ELNA capacitors (and yes, especially DUOREX) in at least the power supplies with PANASONIC FM, or if value not available - FR/FS. (Don't use FC, EVER).
@@hifirulezzz I'm detuning... I don't really wanna see that ;)
My dream are cultures of Nichicon Gold Audio Series, Elna Duorexes, Muses....
@@m80116 At some point I may agree. 555 now sounds so precise, like digital. Very linear response over the full range. For the warm sound, I have other decks :) While I was tuning, I found an interesting thing - Dolby C initially did not match other decks, unless I additionally fine-tuned the tape path on 555esa. Did a very minor change but now all records are fully compatible with Dolby C of other decks, tested on DR-1, Sony 777, and Sony 555esj. Probably the first time when tape recorded with Dolby C plays well on all decks.
@@Astralify Well thank you for chiming in. I don't doubt the risk, but lacking sufficient knowledge I should deduce the assumption that Duorexes are unstable a guesstimate.
Is there anything that can confirm that theory?
I am more prone to believe failure of the bottom seal is the cause, hence powered usage related rather than time (unstable electrolyte formula) related.
What do you think?
Besser wird er danach nicht klingen aber anders 😢😢😢
Yes, it now sounds very precise with full range very linear. With Nichicon I felt a tiny bit missing on the very highs. Also bass is different, deep and very precise now.
The closest equivalent for comparisons to the UES would be the PANASONIC's SU-A (Bi-polar) series, for an apples-to-apples comparison. I don't think they reach the UES sonically, but you can try them and make your own conclusions. Low ESR caps in the signal path not always sound good unfortunately, because some materials might even start to resonate, and these polymer ones's price is just insane. Totally not viable option economics wise, and they are also polar, so they would only be suited for single supply circuits with DC offset. Bipolars would still be better in regular signal path applications with no bias. Also not sure how the polymers would react with half the soundwave where they would be reverse biased, and what kind of distortion that would introduce. Electrolytics are generally forgivable in such situations, but still - bipolar is much better. I dunno... The UES will be truly missed. Nichicon you d*ckheads...
i never measure caps distortion but polymer caps generally have way higher ripple current capability. i dont think small signal would hurt them. bipolar still electrolytics like two polarized caps tied back to back in one package. it's better to use film caps for signals whenever it's possible
