Tube Rolling w/Crack
- Thread starter Dr. Toobz
- Start date
A pair of 6J5s will sound nearly identical to a single 6SN7. I even have a few 6J5s that are 6SN7s with one of the triodes not connected to any pins.
Thank you! I've to admit i'm just rolling trough tubes for the fun of doing so.
On my "just to try" list for my Crack:
Triodes: 6C4, 6J5 etc.
Other dual triodes: 6463/6350 (bias for 5687/7119/e182cc).
Other sockets: 7N7, 7AF7
Now using a 1951, april, Valvo Hamburg ECC40, with Westinghouse 6as7GA with dynamic/musical (and a bit dark) results.

Hi everyone,
Just wanted to say, I'm new here and I thoroughly appreciate everyone's civility and helpfulness so far. Very much a nice reprieve from places like r/headphones...
That aside, I'm a new crack owner and even though I'm still in the very early stages of building, I'm looking to secure some Power tubes to experiment with after I get some time in on the stock tubes and subsequently the Speedball.
I'd really love to find a Tung-Sol (/Chatham) 6080 and/or 6AS7G but it seems as the years have gone by, these guys are getting harder to find and therefore more expensive :/ there is zero value to be found on eBay, (tried with bangybang, wants 80 for a pair) and most online tube stores I've inquired with simply don't stock them. I was wondering if any members had one or both types on hand lying around not being used and would be willing to part with? Obviously not for free, but I also hate paying more than I need to for something...I am an obsessive bargain hunter
Edit: I'm dumb. My kit definitely came with a Svetlana (SED?) Winged "C" 6H13C which is freaking awesome because I was actually going to pick one up because they are cheap and easily available. So score one to Bottlehead for sending these out! It looks just like the one pictured here: https://www.thetubestore.com/winged-c-6h13c-6as7g and here: http://i.imgur.com/c1JoQxU.jpg http://i.imgur.com/Pz88U52.jpg
Thanks!

Hey bud - so here is an option for ya: Chatham 6520. The 6520 is a "premium" 6AS7G only made by Tung Sol, my understanding is that Tung Sol took over Chatham and began manufacturing many of their tubes, including their 6AS7's (also the 2399, which is a 5998 equivalent). So, that is essentially a premium-made Tung Sol 6AS7G. I was going to pick this up myself, but I have enough power tubes, I don't need another.

From my experience with 6080's and 6AS7G (A) tubes. The 6H13C Bottlehead shipped you with their kit is probably the best value for money found for the power tube. I prefer 6H5C and 6H13C over most 6as7g (a) tubes.
Only upgrades are Tung Sol 5998 (and others 2399, 7236, 6520) Bendix graphite plate 6080's (and 7802) and GEC 6080/6as7g (CV2523/A1834), and the premium paid for those is better spend on other "mods" for the Crack. But if you can find one for the right price (as in, cheap), these are worth it.

WOW! See? Exactly what I'm talking about! I have rarely come across such generosity on the internet! Thanks a ton L0rdGwyn! Unfortunately I posted this and fell asleep so it looks like someone else already beat me to the punch LOL. Sucks because that would've been right up my alley. Again, thanks a lot!
I am currently checking stock with another tube dealer that seems to actually have stock at decent prices, although I'm not expecting much... probably too good to be true...
This post is what got me started and the info you were sharing about Tung-Sol/Chatham and the different models definitely lines up! https://www.superbestaudiofriends.org/index.php?threads/bottlehead-crack.120/page-3 scroll down a but for 6AS7G.
Bangy Bang Tubes does not have a particularly savory reputation, I'd suggest doing some research before spending any money there.
Although these are labeled as "Stromberg Carlson", they are Tung Sol 6080s.

This has one Tung Sol and one GE:

GE tubes often times also have acid etched dots on the glass.
Gotcha! Good to know for future reference. So I picked up the 3 from your link. Hopefully 1/3 is in good shape! Seemed too good to pass up. I also JUST managed to get a Tung-Sol 6AS7G from vacuumtubes.net Super exciting!! Thanks for the assistance everyone, I'm ready to roll!! 
He is a very good vendor.Jamwagon said:
