Are you talking about the current production or the original British made tubes?

If current manufacture tube, seriously look no further than Jim McShane. Every tube is carefully tested by Jim.

"Vintage" usually means something not currently produced..., posted on January 8, 2017 at 12:33:30

...does it not? In this case, "British Made"?

I was actually talking about the original British made ones and yes I know what to expect to pay if I can even find a few to buy. But if I can't find anything I might try some of the new production ones and already heard you were the man to see about them from reading other posts. For now I'd like to find an original 12ax7 & 12at7 to add to my tube rolling collection. Thanks for the responses

 

A good example of the modern Genelex, Tung-Sol, Mullard, etc causing confusion with the originals. nt, posted on January 8, 2017 at 13:47:33

Is there any particular reason you must have these tubes? Why not try the current production first before you go out with wallet in hand.

Just my opinion but the current B759 is a great tube whether it be new or old.

For vintage tubes look no further than Brent Jessee Recording.
Good selection and reasonable prices. No affiliation just a very happy customer.
For current production Gold Lions of course Jim McShane.

As you can see there is no reliable source.
You can take a big risk and buy on the open market, with many more counterfeits and other crap, or possibly buy from a good dealer at astronomical prices. The luckiest break you may get is a fellow collector, who would be willing to make a deal with you.
BTW that is not me. The only real B339s(???) I ever owned were bought burned out, but sounded great. I kid you not.

These on the top are some of new old stock I pulled out of the boxes.I also have 7 new sealed in the packages with the data slip that I never opened.


These are used ones that test around 90% and you see Tungsol 6550 black plates in the bottom row.


" I'm going to level with you.I don't sell tubes but I own an awful lot of vintage NOS tubes and to get the best set,they would have to be matched.That is very hard to do especially these days with stocks being so depleted.
The truth is,you are wasting your money IMHO because they are not as great as people once thought they were. When the Genelex reissues came out along with tubes like the Shuguang Treasure KZ,people all of a sudden were realizing with proper biasing and buying from a seller that knows how to match them,the new tubes easily rival or beat the originals as they have now perfected the art of building them.
I have put my originals on many times and compared them to my reissues and I have found that the reissues have a more alive sound while maintaining the accuracy and musical body of the originals.The truth is,the best sounding GEC/Genelex originals were from 1956 to 1964 and I have one pair of those and all the rest I have were made from 1966 to 1977 and all UK made.I never really thought GEC was aiming for the audio market with tubes like the KT88, they were going for the industrial market.The seven that I have new in the sealed package from Ford motor co were used in a plasma cutter. I also got nine that were used and only two were good and the rest were arced over.Being I got all 16 tubes for buying the manager lunch,I'm not complaining.
They made the UK GEC KT88 up until 1988.CJ and Audio Research were both building 6550 amps at the time but chose the GE 6550 over the GEC KT88. At that time,they were priced within a dollar of each other because they were both current production tubes.They both chose the GE 6550 and as expensive as those amps were,I don't think five dollars difference for four tubes was an issue.They liked the voicing of the 6550 more. I have sold off about a dozen of my GEC and Genelex KT88s and I may sell more.I want to warn you tho,if you are expecting this big sonic jump,you are going to be disappointed because it just isn't there being tubes have gotten so much better.
Now the bottom row of New Jersey made Tungsol 6550 black plates,that's another story.Those are very sweet and musical and not dry and lifeless like the UK Genelex/GEC. Again,it will be a chore to find a matched quad of them in new old stock.You may find a slightly used matched quad,but an NOS matched quad will be next to impossible.
You also inquired about 12AX7 and 12AT7s,I think GEC bought those from Mullard or Philips.I have a GEC 12AX7 and it looks like an Amperex bugle boy as I recall.

Thank you Michael very kind of you to write a lengthy informative response. I was mainly looking to own them for collection purposes but I can see it's probably too hard to achieve as they just aren't available to buy anywhere that I can find. Thanks to the member who turned me on to tube world I didn't have that in my dealer line up. I'm very new to all this and just now looking to buy my first non guitar amp for audio use. But I don't know where to start. I want something for hifi audio use that I can use my plentiful supply of el84 and 12ax7 tubes in my collection so I got a lot of reading on the forum to do to educate myself on that topic.
