6SN7 Tube Addicts - Page 251

post #3751 of 4478

Hey Stravos, those Raytheon 6f8g that you mentioned about, got a pair to try out and must say I like them somewhat better than the NU.

Luckily they are quite and are very similar to the NU signature.  Thanks again for another great recommendation.

Pleased you like them George, they are one of my favorite 6F8G's.

 

I have one noisy NU's out of my 6 pairs and I use them as output tubes.

No issues in that duty.

 

Have you tried your 6336's yet?

post #3753 of 4478

My favourite tubes in the Icon are these.

I thought I had bought a spare pair that look identical inside and out but noticed they are not the GTA version Doh!. Will they sound different do you think? They are both 3 hole/staple versions.

I would be vey happy with them.

 

Can you see a production date?

Hmm is it normal for the black glass to become more "transparent" over time?

 

I got myself a pair of Brimar 6SN7GT Black glass. The glass looks quite different from each other but they got the same code - 3B8. Just that one tube glass is kinda "faded" - you can almost see all the way inside the tube - while the other is pitch black.

 

Also do Brimar make these tube or are they rebranded?

 

Tube 1 (can't see anything inside even when light directly shines in):

 

 

Tube 2

 

 

The plate looks like this

Date code is stated as 220. I don't know but seller says 1952. I am happy knowing you would be happy with them.....

Week 20 of 1952.

They are nice tubes worth having.

Enjoy them.

 

khaine1711, some the tubes have a lighter coating.

I don't think it has anything to do with age, it's just the way they were made.

Brimar made 6SN7 type tubes, judging from the top mica and the plates they look original to me.

post #3759 of 4478
No worries, they are real Brimars. A nice older version with the heat radiators on the grid posts too. I wouldn't worry about the difference in black coating, some were indeed darker than others. Looks like a nice pair of tubes.

220, where's the difference of 1942 and 1962?

Haha, sorry Stavros I didn't see your reply. I didn't mean to sound like I'm parroting you.

No problem at all, nice to get a second opinion.

post #3763 of 4478

Stravos, the my 6336 amp is still in Glenn's.  Hopefully I will have it soon.  As to the NU 6f8g have you seen different version of it?  I mean I have some that have a rounder mica and some have like a more rectangular ones.  Both plates are the same though.

Hi George, all my pairs are from the same source and have the same mica.

When you have time could you please post a photo?

 

Mine have the 4 spikes as in the photo.

 

post #3765 of 4478

As you can see in the pics, there seems to be two kinds.  Most are the rectangular ones but I have two with round micas.
