So I have had my SE84UFO25 for a year now.
Quite possibly the best audio purchase I have made in 25 years!
Now I truly hear my source material through my speakers.

In the past year I have gone through one set of output tubes.
Vocals started to shred and the bottom end was sounding loose at about 6 months of use.
Swapped in a new pair and all was right again.

I have been running an EML mesh plate 5U4G for a year, so for those of you on the fence regarding this rectifier, I can report no problems as of yet.

For the input tube I am running a selected JAN GE 5670W with an adapter.

The only voltage regulator I have preferred rolling from those supplied is the input tube regulator.
Believe it or not, I prefer a solid state OD3 in this position.

And yes, this amp just keeps sounding better and better with time!

Dominick,

I started off with the Aqua for about 50 hours, then the EML arrived.
I really should have given the Aqua more time to develop, the EML just opened the sound stage up from the very first note compared to the Aqua.

I took a chance on the EML, first cap is not to exceed 40 uf.
Considering that the globe 80s have a 30 uf max first cap and others are using them successfully, I thought why not give it a try.

That being said, a fair share have reported problems with both the Aqua and the globe 80.
I do not have the tube tech back ground regarding operating limits that others may have, so please do not take my methodology as gospel.  

I have had no issues myself with Aquas in two years of use in Monoblocks, Taboo Mk III and Mk IV and CSP3 and CSP2+, all but the Mk III with the Anniversary Mods. Excellent rectifiers!

The Aqua is a well documented rectifier here, maybe the overall favorite?
I just never gave it a fair chance and I did sell mine on the classifieds here.
I paid the $200 for a 1 year warranty, due to reading about the early failures that a few had experienced.
I will here remark however, that I personally find it odd that a manufacture would offer tubes with a 30 day warranty and then charge extra for a 1 year warranty.
What makes the one rectifier over another worthy of a one year warranty?

While the EML cost $285 ( $290 now ) they do offer a 5 year warranty if you register the tube within a certain time period.
I did register mine but I doubt they would honer it due to exceeding the cap limit.

I guess I am playing "rectifier roulette" by exceeding the max cap limit.
But there are others exceeding the limit more than myself with the 80 rectifiers.

Fortunately there is an abundance of rectifiers to experiment with that are not overly expensive.
I just wish i had the time and patience to try them all.

I almost pulled the trigger on a mesh plate globe 80 ( I have a weakness for mesh plate tubes ).
But I would hate to fall in love with a tube that I could never replace!
 

Yes, the Aqua 274B is a match.
47uf is the value of the first cap for the amp.

If I understand the first cap rating correctly, it is not to exceed the first cap max of the rectifier being used.

The EML 5u4g mesh plate is 40uf, it was lower at one time and EML raised the limit to 40uf.

EML does offer an 80 type but its only rated for a 20uf first cap.
