Call me shallow, but I just PM'd Glenn about his 596 adaptor as I really dig the look of that rectifier. Even if it doesn't sound as nice as others, I'll probably keep it to scare visitors.

Yes, that will definitely do the trick.

I tell my friends (if I have any left) that it's an ionizer from the 1950s. It charges the room with positive ions.

This unquestionably improves the sound.

Thanks to Glenn's adapter I am able to use the 596 tube with my WA22 and Taboo amps. This tube sounds incredible. It is a very organic sounding 5U4 variant. I used it on my WA22 with surprising results--it sounds incredible. The bass is well defined and deep that I had to try it out on my speaker system--the Decware Taboo. I am loving every minute and it is barely 4 hours old! And nary a hot transformer be had amongst them both.
 
It not only sounds organic, it looks organic too--like it's connected to a giant Jack and the Beanstalk shoot.
Now back to listening!!!

When I had my WA22, my wife exclaimed "it looks like some sort of science project!" and it was not a compliment!  This would have put her over the edge.................. 
 

 
Nice finding and pics, Clayton. You did it

, I just pulled the trigger for a pair of United Electronics 596 on eBay

after read only your few words about them. Also PMed Glenn for a pair of adapter for these "organic looking" GIANT. They look as huge as the EML 5U4G and really funny, yup, "it looks like some sort of science project!"
 
The United Electronics 596 just bought from eBay and they look identical as yours, Clayton.

Danny,
So we can use them in our WA5?

Jose, I am just stupidly believed that it can use in the WA5LE if Clayton can use it in his WA22 to replace the 5U4G.

 Also I've PMed Glenn for a pair of adapters and was mentioned I will use them in the WA5LE, so Glenn must warn me if it is not suitable.

 
 
PS. Glenn just confirmed.
 
"I have them in my 300B mono block speaker amps for a week now and they sound better then any of
my 5U4s or 5Z3s."

Clayton,
 
The Tubes remind me of the Pods growing in the lab from " The Thing from another World " Sci-Fi film 1951.  My all time Sci-Fi favorite!  Great dialog, music by Dimitri Tiomkin plus some Theremin!

Just digged out a great post about 6SN7 tubes "The 6SN7 Identification Guide", all Woo amp users with 6SN7 tubes worth take a look.

dannie01--Well if you can't use those 596 tubes you just got off of eBay, then you can just mail those two tubes me.

Wait... I just woke up and didn't even get a chance to take a number! (overheard on the loudspeaker... "Now serving number 002." Silent One looks down to find his ticket is numbered 105 and wonders how long he'll have to wait).

 
Post Script:  Yup, Glenn don' clean sold out!

A bit of reading reveals the 596 is considered a substitute for the 274A under the right circumstances.  That means it must be at least somewhat close, electrically, to the 274B (the only difference between the 274A and 274B being the pin configuration).  I'm guessing it is an "uprated" 274 type tube that can handle higher voltage and the like.  This might be akin to getting an original Western Electric 274B at 90% off depending upon how you want to look at it.  Of course I may be wrong too.......

actually, the 596 is not a direct sub for the 274a. the 596 draws 3.0A of current, whereas the 274 types draw 2.0A to 2.5A depending
on the manufacturer. it may work fine onf the woo amps though. the 596 were supposedly used for aviation purposes and are
high elevation version of the rk60/1641 rectifiers, which were applied at high voltage (up to 2100 peak inverse V) with maximum dc output
of 250mA (but united electronics, which made the 596, claims the 596 can take up to 2300 piv and can put out up to 275mAdc).
it's closer to a 5u4g than a 274a/b in general.

Does anyone know where to find those 596 tubes? It seems like ebay is all sold out. Do they come up every so often?

 

[mikemalter]

How do the 596 tubes stack up against the EML or Sophia?
