If they have staggered plates they are the same. If the plates are parallel then it is a newer version that came after GE took over kenrad. General consensus is this type does not sound as good.

 

[SpudHarris]

This is the top view. Are these the good ones?
 

 

[Xcalibur255]

Yep. Those are good tubes. You can see the position of the plates by looking at the grid posts.

 

[SpudHarris]

That's great news, thanks as always...... they will be here Saturday so looking forward to an extended listening session.

Cheers - Nigel

Check them for microphonics, the kenrads are notorious for being noisy.

just recently bought a brown base tung-sol jan 6SN7WGT in excellect / strong condition. seems the WGT version is rare to come by on ebay as dictated by this post. there are some WGTA there and here. anyone have knowledge of the sound differences between them?

 

[rosgr63]

The WGT are the better tube for me.
 
Gold Label
 

 
Here is the 50's version

 
Her's the Tung Sol version with the horse shoe getter

your PM earlier helped me clear it up. thanks for the response.
 
and i won a bidding what seems to be a NOS sylvania vt-231 for $20.15 shipped if his test scores are accurate. can't wait to hear the sylvania WTG, TS WTG, and sylvania vt-231. i slipped an auction on a almost NOS rca vt-231 grey glass. that was pretty stupid of me... i could have gotten it for $25 shipped. i was watching breaking bad and got caught up in it. grr

 

[rosgr63]

That's a very good price for a good RCA Grey Glass.
Never mind better luck next time.

Wow.  I've been gone for almost a decade and this thread is still going! O.o
 
6SN7s are magical.  I think I should take a photo of my holy grail collection ^.^

 

[Len]

Ok, I do have a question having been away for so long.  What are some current 6SN7-based headphone amps?   I think I want to dip my feet back into headphone waters.  I've used a bunch of Singlepowers (read bout Mikhail's sordid end), Cary 300SEI, Wheatfields, and Berning but I doubt any of these besides the Cary are available anymore.

^Hi Len, do post a pic of your holy grail collection...we love pics! Two 6SN7 tube amps immediately come to mind: Apex Peak (one 6SN7 at a time) & Eddie Current Super 7 (uses one 6SN7 driver and 6 output 6SN7 at the same time).

 

[Len]

Thanks Cee Tee.  I'll take a look at both.  I don't know if I can afford running seven 6SN7s for the EC
 
Here's a pic of my main NOS/NIB 6SN7 collection.  It's about 20% of my NOS 6SN7 collection, but the tubes in this case are honestly holy grails and took forever to assemble, especially in NIB condition.

Holy crap - that's the most expensive 6SN7.
 
Wish one day I could afford to try those 33S30B or the 6SN7W metal base 

. Also are there significant differences between the three Sylvania 6SN7W?

 Lovely, Len, just lovely!
