Yours has the holed plate whereas mine looks like dimples although you can see light through some of them.

My best guess is both were manufactured by Fivre, but at different times. Generally, vertical support rods are characteristic of older construction.

I have only seen this tube mentioned a few times here.
Here’s my very limited information.
Bendix 6106 rectifier.
Made in Red Bank NJ.
Intended use in Nike SAM missile.
Rated up to 80000’
Very unique plate structure.
There appears to be a ceramic rod in the middle?

Does anyone have sound impressions?
I hope to have this tube tested later this week so I can roll it.

Edit: Tube tests worse than it looks

Hi, does anyone know if this ultron rebranded brimar?

 

[Bozz_Keren]

Or this one rebranded RCA, is this any good?

I had a 422A and sold it to one of our fellow Head-Fiers. To be honest in my system it wasn't anything special. That said to each his own. Last I heard from the person who I sold it to who runs a Woo Audio WA33 elite edition as well as one of the TOTL dCS DACs they also thought it was okay.

No judgments though. Every single wire and component in one's system is system dependent and user preferences dependent.

If you love the Western Electric 422A then that's wonderful. My view regarding this hobby has been and will continue to be that the gear, equipment and accessories are only a vehicle to enjoy the music.

I read similar comments from you b4. I totally fine with that. I have more than one pairs of NIB 422A. So，yes, my system and my ears may different than the others.

He sold it to me and it is long gone. It just did not measure up to the Tak 274B. I have tried the KR274b, WE 422A, Sovtek 5U4G and USAF 596 and found the Tak superior to all. I have kept the USAF 596 as backup. Might try the Elrog 5U4G sometime in the future.

As has been written before, there is no such thing as one "super rectifier" that is the absolute best in every system. For sure, the WE 422A shines in some systems, but in others, it's just so-so. So keep this in mind before pulling the trigger, especially if you have never heard this tube in your own system.

Hi gibosi, can you help to decode these TS 5998 tubes and also the measurements?. The seller said that he used amplitrex at 1000 tester where 15500/15500uMhos is new ( i do not speak this language), thanks. They are working beautifully with no noise at all.

322 = Tung-sol
5645 = 1956, the 45th week
3 = not sure, but it seems to indicate the factory

I don't own a tester so I can't speak with any real authority about the measurements. But IMHO, the numbers are close and that's a good sign. And since they are "working beautifully with no noise at all" I suggest that you just relax and enjoy.

I have done the same thing. Used a lot of different rectifiers and gone back to the Tak 274B.
I've had two sitting in my drawer for a couple of years. I just dug them out a few weeks ago and have been impressed.
They are a little lean. However my HP's at the moment are dark. So they suit.

The Tak 274B does this reverberation thing (very hard to describe) that I haven't heard before on another rectifier. It's a good thing. I like it a lot. It gives a more analogue experience. Every time it does it (only some notes) it makes me smile.

And that 422A circulated around could be a defect one too. LOL

Anyone in here tried an Elrog 5U4G in an Ampsandsound? I have the Bigger Ben Rev2.

Great snag....don't worry about anything...just enjoy the music with those beauties.

 

[normie610]

Shame they're so large as I doubt they would fit in my Manley 300B pre due to the rectifier sockets being very close together

True. I’ve explored Elrog 274B in the past, and went back and forth with their distributor in Singapore regarding the size (and sending them measurements), and they concluded that it definitely won’t fit the Manley. The spacing is just too close.
