I know nothing about your amp... But the 6SN7 heaters draw 0.6A whereas the 6922 heaters draw only 0.3A, twice as much, so be sure your amp can handle this. Otherwise, you could damage your amp.
And yes, if you can safely roll 6SN7, you can also roll the Psvanes CV 181, which is just a "pretty" 6SN7*.
There was recent chatter in one of the threads around here about the Tung Sol 6sn7 GT Mouse Ears, so I thought I'd try one. I'm using a Project Ember ll and have two Sylvania 6sn7 GTB's, a Ken-Rad 6sn7 GT, and another Sylvania 6sn7 GT to compare to. One of the Sylvania GTB's is a standout and my favorite.
I found one on eBay that said 'New Listing' , whatever that means. It was reasonable so I grabbed it. It appears to have been a good decision. Comparing to my best Sylvania, it is cleaner sounding with better upper detail which gives the sensation of more air. Better midrange, vocals. The bass is not as strong but tighter. But that is easily remedied with the Schiit Loki. It also has a silent noise floor unlike the Sylvania that has slight noise on the left channel.
The tube of course was listed as a Tung Sol but there is nothing on it that I can detect what, exactly it is. I'm thinking maybe that the tube was funky and the vendor might have cleaned it up, removing any markings. Does that sound plausible? The other thing is that it has a brown base. (It might be a little hard to tell in the pic) I can't find any information on brown base Tong Sol 6sn7 GT Mouse Ears.
Is there a way to tell exactly what this is for sure?
Edit to add: It's a very dark brown on the base. Maybe that's not considered brown?
Great info!, gibosi!.I know nothing about your amp... But the 6SN7 heaters draw 0.6A whereas the 6922 heaters draw only 0.3A, twice as much, so be sure your amp can handle this. Otherwise, you could damage your amp.

Good to hear you're enjoying them chy, if the reviews are correct then I guess you still might have someway to go, enjoy the burn in, I'm hoping mine will arrive tomorrow and then I can begin the long road to audio nirvana!These are my endgame tubes. They get better every day!

Check out the Ember Tube Rolling thread. Several Project Ember owners are doing this so you'll find info on adapters and favorite tubes.
Some nice tubes their @L0rdGwyn. My recommendation would be the 6N8S Foton, 52-55, Ribbed anode, strictly between those years, nothing after, they're cheap but rare, they offer a superb spacious, transparent, detailed and dynamic/punchy sound. I know Foton tubes have a patchy reputation but the 52-55 ribbed anode is a cracker, a genuine sleeper imo, if you are interested here is a link to where I bought mine.Hey people - just started going through this thread a few days ago. I am upgrading my Bottlehead Crack to a Crackatwoa, going to be doing some modding and decided to give the 6SN7's a go as my drivers. Was hoping for some recommendations as far as quality 6SN7's that are around $75 or less in price. So far, I picked up a Sylvania JAN CHS 6SN7W short bottle with black base and green text for $70 (not sure of the exact year, but presumably 1940's) and a 1953 Hytron 6SN7GT NIB for $30.
Some other tubes I am looking at are the RCA VT-231/6SN7GT gray glass from the 1940's (seems to run around $50) and the Ken Rad VT-231 black glass (seems to run around $75). I know some of the Tung Sol's are highly regarded, but the round plates seem to be out of my price range.
How did I do on my first purchases, and are the RCA and Ken Rad good pick-ups as well? Any other recommendations would be appreciated. Cheers!
P.S. Below are the two tubes I've purchased. I also run the Western Electric 421A and Tung Sol 5998 as output tubes on the Crack.
