FWIW, I'd probably take this over the Rubycon anyway, even if it does cost more. SamYoung Electronics|SamYoung Electronics NFA 400V47 18*20|Aluminum Electrolytic Capacitors - Leaded|LCSC
My second choice would be Ymin|Ymin LKML2502G470MF|Aluminum Electrolytic Capacitors - Leaded|LCSC but I tend to like short fat caps.

Are those well known brands in China? The good thing about buying those is that it's much less likely that they're counterfeit. No point in counterfeiting an obscure brand when it's just as easy to print a famous brand name on it.
I recall a post on another board where a guy was saying that he had upgraded his cheap Chinese amp with a Sam Young cap he had purchased on Aliexpress or eBay. He included a link and it cost about 5x more than a nice Nichicon. After quite a bit of searching, I found the specs for the cap and they were absolutely horrid.
Apparently, they make different levels of quality, like the well known brands. Still.
SamYoung is Korean, and Ymin makes well spec'd caps for the money. Not a common brand outside of Asia though.
I now use Hayseed on everything I restore with old can caps. Great people to deal with and never an issue.
So are the Authenticaps stuffed with discrete radial capacitors like the Hayseeds?
Or are the Authenticaps a "toilet roll" construction like the CEs and vintage Mallory cans?
I don't feel it is expensive. Cheaper than a lot of multicaps and you get exactly what you want. They do custom as well. They are so easy to deal with and so fast. Customer service is extremely good.
You can generally tell by the temperature rating. Original construction like CE are rated at 55-65c. Restuffed are generally 105c
Pretty sure my VTA ST-120 gets hotter than 55* 2 inches from a pair of KT120s, the Authenticap is rated at 105c.
This data sheet for Authenticaps states they are 70C. What does this suggest about their internal construction? https://www.die-wuestens.de/kd/KTL.pdf
Have a look at MULTI-SECTION CAPACITOR - Dynakit Parts This sure looks like a rebranded authenticap and says it uses modern caps internally. Also rated at 70c
You probably can't do any better than Hayseed Hamfest. They're very reasonably priced, built with best quality non-PRC components exclusively, and have proven to be excellent folks to deal with. Solid folks, solid product.
My years-ago experience of exploding (not an exaggeration - black goo all over the room) can caps "made on original Mallory machinery" from 20-25 years ago has made me cautious. My building partner has used Hayseed Hamfest parts in all kinds of Golden Age gear restorations over the past year, and all have been very successful, and 100% easy and helpful transactions.
All good fortune,
Chris
