Well, I don't know... I've heard a lot about the benefits of oaken (or even hickory - gasp!) enclosures for your coupling capacitors. Those very knowledgeable in such matters have described the resultant sound as "Full and very dense with ear-coating tannins but also attractive fresh fruit, pretty acidity and a long finish. Rather chewy and needs time." Pretty hard to argue against something so compelling as that! :rofl:

Sorry, I sometimes get my wine and capacitor reviews mixed up. The same meaningful semantic content confuses me...

Mr. Both works a long time for Valvo/Philips (development manager, manufacturing electrolytic capacitors).
There are several reports from him regarded caps. search for "Bad Caps".

I have mentioned, that Mr. Both worked as an advisor for this company from China:

(go to last page of this pdf for more details concerning older technical papers written by Mr. Jens Both).
Under
https://jianghai-europe.com/capacitor-competence-center/fachartikel/
are several technical papers as PDF available for download written by Dr. Arne Albertsen - both in German and English language.
In the attachment any examples.
I guess, that this brand is also a good choice for new projects, modifications and repair service and similar quality standard as on the brand FTcap is to expect.
Any experiences ?

Hi tiefbassuebertr,
Please don't repost earlier posts.

Anyway, the important aspects may be some of the papers such was posted from Wurth. I'll take a Wurth capacitor over a Philips any day, they made the cheapest stuff going for years.

Have you read and understood any information or papers you posted? If not, read them first to make sure they are useful first.

I haven't seen those here, and Philps only had tag type connections from what was carried here.

The normal Philips board mounted capacitors were not very good.. They were used in cheap amplifiers, generally a good place to start replacing things. They were also used in test equipment (Philips scopes) and tended to fail as well.

I don't have time to investigate a ton of links, I need a directed reason to spend the time. I do look at the data sheets for all parts when selecting components, but no way will I remember parts I reject.
