The crack uses a 12AU7 driver tube, not a 6SN7. Are you planning to use the 6SN7 in a different amp? Or to modify your Crack to accept a 6SN7?

I was under the assumption that I can you a 6sn7 tubes,with an adapter:

Please correct me,if I'm wrong on this..
 
Tnx

You probably can - although it's always best to check with the amp's maker.

As for the tubes you linked, they are not my personal favorite, even of VT-231's. I like the Sylvania VT-231 best, excluding the Tung-Sol black glass round plates, some of which were labeled VT-231 (the US military designation for a 6SN7). Those Ken-Rads will have a very robust bass, but most people I know find them a bit muddy, as do I.

So,I can use them-Correct?
Tnx for the tube info, 
 
 others I've picked upi,& yet to use are:

Do you have a honest reliable seller,where I can buy adapters?
I find it difficult to order from China ,sometimes?

 

[Skylab]

I'm not saying you can or can't use them. You need to ask Bottlehead.

The two tubes you already bought are nicer than the one you asked about, though, IMO.

I bought a 6SN7 to 12AU7 adapter off eBay.  It works fine.  There is a lot of discussion on this topic in this thread.  Somewhere in the thread, Doc from Bottlehead chimes in and says the 6SN7 with an adapter works fine in the Crack amp.

Here is what Doc said specifically about 3 weeks ago.

Tnx BmW,
Bottlehead was the first place I checked,but thanks for the thread...just wanted to see what other tube choices I have.
Is your adapter,the one I linked above??
 
My main concern was if the adapter ,will degrade the SQ of the tube.
As there are thousands of tubes to choose from,in the 6sn7 family..I thought I'd  try to get a Ken-Rad,some think it is a good tube,but,it may not work for me...I am not a muddy basshead
As of now,for my Crack,& the HD800's..I have chosen a Tung-sol 5998 with a Amperex bugle boy longplates,and,I'm extremely pleased
I listen to mainly classical,acoustic guitar,& other s.

As long as an adapter is decently made it can't hurt the performance of a tube. Its just passing the electrical connections from one set of pins to another.

Yep, that is the one.

 

[rosgr63]

A friend is selling some nice British and Dutch made black base B65's and L63's.
 
The tubes are used but are rare finds and well worth having IMHO.
 
I am actually getting a couple but more are left, if anyone is interested send me a PM to give you his details.

Great! Is there a tube out there with similar sound and character that I could relate to as an example of the B65's sonics?

 

[Neogeo333]

maybe the 12v version of it the b36?

 

[KingStyles]

Just curious, has anybody ever tried these? Meixing Mingda 6SN7

 

[rosgr63]

Josh if they sound as good as they look it would be fantastic!
 
George you are right, the B36 do sound like the B65.

No, I haven't but I've been eyeing them. They look pretty, and are a bit pricey for me right now. I'm interested in how they sound too.
