Dave did you get an adapter to go from 6F8G to 6CG7 directly? Or are you using two adapters? I'd like to use some of my 6F8G's in "our" DAC but I'm concerned about stacking two adapters and a relatively big tube on a nine-pin miniature tube socket...

Glenn made me a 6F8G>6CG7 adapter so I am not stacking them.

or it is Sylvania?

Pinnacle were a rebrander.

 

They used tubes made my Mullard (ECC32 etc.) and others.

 

To be able to tell if it's made in CCCP look at the getter, the flying saucer type usually is a give away.

 

I cant tell from the photo.

Hey guys,

I normally pick up used tubes as they are cheaper but recently grabbed some NOS RCA 6SN7 and I'm enjoying the sound so far. When one of the tubes is warming up, maybe the first 20 minutes, there is occasional static through one of the channels.

As mentions, the tube sounds fine when it's going, any ideas what it would be?

ok then....confirmed it's Russian tubes

 

 

thanks guys..

That pinnacle 6sn7 looks like it has ladder plates to me. RCA would be a likely possibility, or maybe GE or Raytheon.
post #3584 of 4150
That picture was kinda blurry, but those look like flat ladder plates to me, and that's not something that typically you see in the Russian 6H8C, which typically have more of a t-plate structure.

EDIT: looks like X and I agree on that wink.gif

That's what I thought I saw, too. But can't be sure based on that tiny photo.
