No....but it will not work in Glenns OTL.....I believe Glenn said that this tube would die in his amp.
 
Maybe i will contact Langrex

In the relatively short time I have been watching these, all the GZ37 I have seen were manufactured by Mullard, regardless of the silk-screened brand. Further, I have seen Mullard-made GZ37 designated as 53KU and CV378. And to make things a bit more interesting, I have seen Mullard-made GZ33 also designated as 53KU and CV378. Thus, I always recommend that you examine the Philip's tube codes before you buy so that you know exactly what you will be getting.

Yeah, that can get kind of confusing  

 
gibosi....do you have a GZ37 for your Glenn amp ?

 

[gibosi]

Yes, I currently have GZ32, GZ33 and GZ37. However, I haven't gotten around to compare them yet. As we can't run the Brimar 5Z4GY in the Glenn, I am keeping the GZ32 in as a default, per DSG's evaluation, until I can spend more time with the GZ33 and GZ37.

Some smart dude has a large collection of 596's and is dribbling them out over a long period of time:

(Search completed listings, people are actually paying these prices.)

Is that not an insanely good price for a matched pair of those?

 You missed the tubes dual marked as GZ33 / GZ37 Easier to  think of all of these as either fat bottle (MOV) or thin bottle (Mullard).

  Have you tried the Brimar 5Z4GY?

Too wimpy to be used in Glenn OTL

. Cannot handle the current draw, will blow up.

I purchased 6 of them at $50 a pair. Word on these boards causes popularity to soar and the tube trolls catch on and BAM! the price rockets.

Dubstep Girl,
3 weeks ago I received my Woo Audio WA6 and based on your thread I purchased 2 RCA 5U4G (ribbed plates), great tubes. Also I was wondering if you had any experience with a Bendix 6106.Thank you.

Anyone here heard the the 596 rectifier and compared it to the brimars from langrex? 
 
I am thinking of buying a pair of 596's but am wondering if they will be an improvement over the brimars? 
 
 
Also - Has anyone heard both AVVT 300b super linear and if so would these be an improvement over the EML 300b mesh?

That would be interesting to know ,if you check out at the beginning the 596 compared the RK 60 not that much of a difference it seems it depends on what one prefers and some liked the RK60 better .The brimar you are refering to is the 5Z4GY i have those and the RK 60 and if thats any indication on how much better the 596 are well i just saved myself several hundreds.

I think the 596 is better than brimar 5z4 because of wider sound stage from a clearer/airier presentation while still having bass impact. 5z4 sounds warmer with more bass slam while there is some imaging issues.  I would get a brimar u52 for not that much more than 596+adapter.

If you could use a percentage on how much better you think the 596's are compared  the Brimar 5Z4GY how much would it be .

I think both tubes are good enough it is more about which sound signature you prefer.  I think I just prefer the 596 generally but I use Brimar for bass slam rock as some would for edm.  Brimar is good for price but I would not buy if it were as much as says mullard 5ar4 are going these days.  I would not pay more than what they are being sold for now at Langrex.  Brimar would be really good if it just imaged a little better I think.
 
I think the real deal at langrex is the mullard 6080.
