6SN7 Tube Addicts - Page 268

Interesting, thanks :)

 

I like NU GT.  Sounds great in my MPX.

I think there are too available to make it 'special' compared with rarer ones.

Thanks!

I didn't see your question earlier. Didn't mean to ignore you. It basically said for loose bases to turn them clockwise until tight and use a couple drops of nail polish to secure the base. Since your base is completely off the clockwise direction part isn't very helpful. As for the original post its somewhere in the last 268 pages.wink.gif

Yes, since the base is completely disconnected, I am not sure nail polish will work, so am thinking about a couple drops of super glue or epoxy. But for the time being, the twist-tie is working fine. :)

Anything to say about the French Visseaux 6SN7 ?

I've bought a pair brand new, they are built like a tank !

I'll plug them in a while.

I'm really enjoying this one ,quickly became one of my favorites 6SN7s 

probably one of the smoothest 6SN7s I own with wide soundstage,  good bass (unlike Sylvania VT-231/silver label) , and treble,pretty fast but smooth with exceptional detail and good instrument separation-liquid mids

Nice looking glass in the drive slot...

I am looking at purchasing a Mullard ECC32 / CV181 & the test results for it are as follows :

 

A1     8.6mA   1.7mA/V      95% 65%

A2     8.0mA   1.7 mA/V     88% 65%

 

I have no idea how to read test results, does it mean they are good ? Any help will be highly appreciated.

 

Thank you.

I would be suspicious that the seller tested them using settings for a 6SN7.  Without knowing which tester was used and the settings used, those values are basically meaningless.

 

For reference 6.0mA and 2.3mA/V are spec for an ECC32.  The first number is the plate current draw and the second is the transconductance.

Got these beauties today but cant test them.  If they test NOS or near nos I think I did good.  

Guess what the back lettering says?

Received a Brimar 6SN7GT today. Managed to pick it up for $5. Apparently the vendor didn't realize what he had and the picture quality was quite poor, so I was the only one who bid on it. :)

 

 

If I understand the 6SN7GT Identification thread correctly, this is apparently the same as the STC/Brimar 6SN7GTY / CV1988, as it has what I guess are "small anode plate extensions" extending vertically above the top mica.

@ Neogeo333

 

Lovely. :wink: 

post #4017 of 4437

Thanks SO.  Maybe I'll sell a couple and finally get a Glenn's 300b amp.:smile:

I'm working hard at getting another creation from him as well. Can't wait to drop the plate and peer inside the 300B with my 48" Black light! :tongue_smile:

I'm not sure about the "extensions". Are these the ones with them?

 

 

They are not connected to the anodes, though...

Even though they are not connected to the anode, I can see where someone might think they are anode extensions. And these tubes. with 2 extensions of some kind, match the description much better than mine, with anode rods extending slightly above the mica. So it now appears that my tube is the later version 2. Regardless, for $5 it is a pretty good tube. :)
