Does this also happen with other rectifiers with different intensities?

Personally, I have never had a single problem with NOS or used rectifiers that are up to 80 years old and shipped in from all over the world, even in a way that is not fully 'dampened'. I find it absolutely astonishing that an Elrog rectifier should arrive not working or in a condition that...

Absolutely clear! Thank you Col!

It's a pity because a more impactful Takatuski would have been the final rectifer!

@ColSaulTigh : However bass slam or bass weight is not in the lines of the Takatsuki as fas as I understood from your review (?)

Here is a great review of the Takatsuki Denki TA-274B versus the KR Audio 5U4G "Riccardo Kron Anniversary Edition" by @ColSaulTigh : https://www.head-fi.org/threads/rectifiers-why.305127/page-3#post-16963354 Many thanks to this guy for a very accurate comparison!

Thank you very much and congratulations for your equipment!

This's to satisfy my curiosity : do you prefer the KR RK 5U4G respect to the KR 274B-HP since you chose the first for the comparison?

Dear ColSaulTigh, you did a GREAT job! Thank you very much for a rare in-depth review of the Takatsuki Denki TA-274B (and the KR RK 5U4G)! Do you allow me to point it out on the main thread about rectifiers (...

I currently use black-base/black-plates early 1950's Cossor 53KU and I'm looking for even better pace, rhythm and transients. I'm certainly looking for an extended and fast rectifier. An almost definitive one, possibly :relieved: Thank you again!

Dear ColSaulTigh, please use your preferred test music with an eye to rhythm in order to establish if the TA-274B has the scepter of best rectifier in your collection. The comparison with the KR Audio 274B would be particularly interesting. Thanks for your time! Gianluca

Dear ColSaulTigh, did you formulate an idea about the Takatsuki Denki TA-274B you want to share? Thank you very much!

Gibosi, how do you think the 53KU would compare to the Takatsuki Denki TA-274B? Are there data that allow us to express an opinion? Thanks!

Not always, I agree. There are exceptions, but not in this case IMHO. The earlier black plates and black base 53KU sounds better than the brown/grey one to my ears. Not by a large margin, of course. We're talking about details, but details count.

Good!

I own the Mullard GZ37 and it's a nice-but-not-special tube. Better than others but nothing incredibile. Hopefully you didn't pay an extra for the Cossor logo

Is this the skinny bottle? Please post more pictures when you receive it 😉

Dear Gibosi, it's good you to explain that colours don't affect sound quality, but for what regards the Cossor 53KU colours should mean something : "tubes have the "K" factory code & were made in the UK in the 1940s or early 1950s. They are considered superior to the later Cossor 53KU with...

Wonderful! I use a pair of rare Black-base 53KU's and the getter is identical. What a sound... Gianluca

Hi, did anyone try the super-expensive Telefunken EC8020?

Congratulations! I've never had the luck to listen to it...

IMHO this tube shows features that are compatible with a definition of fake. Why to label it U52? It's totally different.

This should be a genuine black plate / brown base GEC U52, made in England. In my system it's second (by a large margin though) to the black plate / black base Cossor 53KU only. Gianluca

I'd go for NOS. I bought my NOS original 60's Telefunken E88CC pair (not made by JJ :wink: ) from Tubeworld Express and it was great to deal with Brendan!
