Howdy.  I have some JAN CDR 1641  RK60  and they have writing on the top of the top plate.  Has anyone encountered this before? Asked this a while back on a Woo thread and did not get a response.
 

 
Thanks.

Thanks for the response guys.  I have not previously encountered the writing and was curious if this was strange. Now I know it is not.   And @abvolt, thanks, am enjoying this quite a bit.

Ok my fellow/fellette rectifier , friends. I need your help. I purchased a supposedly Brimar 5Z4G , from a local guy who sells all kinds of tubes. All the labels are rubbed off except for the 5.

We are both curious if it's what he and I both think it is. The one thing that's confusing is the getter style. He had another 5Z4G , that he was getting ready to ship out , and everything was absolutely identical but the getter. The one being shipped was an "O" getter. The one I got has this getter:



Not sure what you call it but it looks like a rectangular type upside down plate of some sort.

Hopefully one of the tube vets can chime in. My only knowledge of tubes are 6922 variants.

FWIW , It sounds amazing. Very organic and natural sounding. The mids are absolutely sweet. Very nice 3D , holographic, layered presentation. Reminds me of a Holland Heerlen Valvo or Miniwatt E188CC/CCa.

Generally speaking, foil getters were the norm in the early 1940s and halo getters were the norm starting around 1960. So if otherwise, these two tubes are identical, it is likely that one was simply manufactured 15 to 20 years earlier than the other.

Many thanks my friend!

Cheers

Seems a little cheap for a Psvane 274B at $85 new? Replica of a replica?

Didn't realize there were two different Psvane 274B's. One is a "regular" 274B and the other is the "WE274B" replica.

I have a GEC U52 with one broken pin. Will it still work ?
 

 

[gurubhai]

^Are you sure that it is a U52, because that looks like a B4 base to me?

Pics of the tube. It normally has 5 pins, but this one has one pin broken. That's why I wanted to check if it can still be used ?
