Yeah. Another project involved finding good replacements, I was finding it difficult to locate similar three point mount caps, still am!
Vishay 021ASM were used to replace the axials, at the time no cap was found with the three point mount.
The good thing was the mechanical stability of the mount, looked like a good idea.
The sikorel 125 have a mount version that looked similar, souring anything less than 100's stopped that.
Kemet PHH223 was the other, but the info was 'shelved for later'. a similar sourcing quantity frustration.

RDE I haven't heard until now, but probably you mean "ROE" - the Logo on Elcaps for Ernst Roederstein (on the foil versions was the Logo "ERO")RDE caps are a areal source of trouble in Revox and Studer equipment.
Concerning a lot of trouble on this brand you are right - especially on certainly series like "EK" under
Roederstein 'BAKELITE' series EK capacitors - "Living Legend" OR "Looney Legacy" ...?
often to find even in top class devices from Krell and Mark Levinson, so as the low voltage versions below 40VDC from Roederstein's EDG series (unfortunately also often to find in STUDER/REVOX devices).
By consistently collecting and storing defective electrolytic capacitors over 30 years, it was possible to clearly identify which series were particularly affected by failures.

Hi tiefbassuebertr,
You're correct. I don't pay much attention to the exact brand name for poorly performing components. Having been warranty for Revox, I have had my fill of these terrible parts. I just recognize and replace.
There are many bad brands of capacitors, but there is no "best" capacitor. It depends on the application and many good brands are in fact equivalent.

I prefer Mundorf mlytics.
They even survive short circuits for extended periods, sound excellent, and all have very similar values.
What's the point of one 10,000uF Sikorel capacitor if the second one differs by 15%! I'd rather buy Mundorfs and not have to buy a dozen because I have to measure the correct values. Mundorf mlytics are always the best choice for me!

The reasons heard to justify using boutique parts are sometimes amazing 😉
Please explain, what does this mean ?I prefer Mundorf mlytics.

Also one of my favorites. Interesting to know are a listening test to this BHC version:I prefer Mundorf mlytics.

Some advices to Mundorf caps:
This may seem like a silly question but I want to make sure. Unlike the dimensional drawing below. My MLytic caps do not have the terminals clearly marked as positive and negative. Can I assume as in the below picture that the gold line with the little block indicates the negative?

Apologies, yes, ROE.
Mundorf are relabeled F+T caps.
The slit foils caps have more 'tabs' to connect along the plate length (T-power BHC Aerovox ALN20S1108DF since relabeled) ,
these were designed by Denis Morecroft of DNM, specifically for power supplies in audio to reduce the current path.
It's interesting that Tesla cars newer larger production 4680 battery cells take that idea to the max, facilitating extreme current discharge, essentially an extra width foil that becomes a long perforation of tabs folded to form the negative terminal:

RWTH Aachen discovered the 4680 cells to be inferior to those by BYD indicating there is room for inprovement.

looks like a pejorative comparative, typical of academia. Both types have raised the bar.
Scalability in manufacture, whilst reducing costs was a large part of Teslas 2022 intro.
We know development in the battery world is ferocious, but that's drifting off topic.

Come on man...you just take two Panasonic Aluminum Electrolytic capacitors back to back like a super capacitor. Cheaper than dirt.We can't always afford polypropylene capacitors, much less
Teflon (tm), so we often make do with electrolytics when
we need those higher values.
There's all sorts of caps out there with claims to being better,
and they certainly are more expensive.
My favorite is the Elna silk capacitors, available from Digikey,
and really cheap. The measure spectacularly, sound great,
and the manufacturer's translated description of why they
sound better is a Babelfish classic.
So before you run out and spend a lot on the highly hyped
spendy caps, try the Elna silk caps.
There's hemp in them, too.
