6SN7 Tube Addicts

Is this the adapters?

 
The eSlay ones work and as long as there is not interference they work well. The best ones are the Glenn adapters. A lot thicker wires.
 
I used the eSlay ones and my remote control lights caused noise in the tubes. They had no noise as long as the lights were off. So they work okay.
 
I then got the Glenn adapters and they were more solidly built and no interference at all. Well worth it.
 
Pics below of Glenn adapters. I had two different sets made for my WA22.

Let me crash this party and say if you want a really good 6SN7 IMO not just the one you have heard get a Sylvania GT.  They come in different types the chrome domes,  which people think sound better with the mil spec. metal base, making them expensive, other mil spec,   which sound great to me and the early civilian also a good tube.  The next variant has a bottom getter which are all erroneously called Bad Boys but do look like them.  They sound good too and come in mil spec. VT231.   You might want to try them, they are all immensely popular.  Nothing against the RCA which is indeed a  very very nice tube as is the NU.  I own them all but have not invested yet another fortune in the 6SN7 predecessors and it's adaptor,  I understand they do sound extraordinarily good.

I agree, the Sylvania's (right vintage) must be on anyone's top 5 list of the best 6SN7's out there, at this level it all comes down to system synergy.

I find the fact that you can get away with running a 5Z4G rectifier in a WA22 to be pretty interesting.

Is this anywhere near what you are talking about

Bought a tall Raytheon 6SN7GTB from Minnesota. Made in Japan. Surprised me, but impressions from earlier in the thread are favourable.
 
Seems to be comfortable in my amp.

Looks like the same plates as the RCA's. Different micra's tho. How is the sound?

 

[Xcalibur255]

It's a Hitachi.  Some people like them quite a bit.

 

[Badas]

With plates do they get mixed around with other manufacturers?
 
For example those plates above look like RCA. However I have seen those plates on Raytheon, Kenrad and Tung-Sol 6F8G's as well.
 
The NU 6F8G plates I have seen on Italian tubes, RCA and Kenrad 6F8G also.
 
You kinda see the same plates but different manufacturers implement them differently. I have a RCA and NU 6F8g with the same plates however everything else internally is different. Similar sound but not exactly the same.

 

[Xcalibur255]

You have to look for smaller details in the construction.  Many manufacturers made ladder plates or t-plates but all had small variations in construction techniques that make them identifiable from one another.

Sounds fine in my set-up (comparable to my Sylvania and Metz alternatives) which is a bit unusual: OTL balanced anode/cathode output driving a HD580 at the moment.
 
The 6SN7 has higher output impedance than the amp's standard tube 6AS7G, but fine for the 300 ohms Sennheiser.

MDR, If you like the sound of this substitution with high Z headphones, you should try subbing a 6BL7 or 6BX7 as well if you haven't already.

Someone was looking for these, I think.  I am not selling them, but saw them.
