As I read through this thread, I think i need to buy one.

Give me an advice.

 

I just use the cheap chinese socket savers.

 

http://www.ebay.co.uk/itm/2-X-9-PIN-TUBE-SOCKET-SAVER-FOR-12AU7-12AU712AX7-ECC88-/290835055818?pt=Vintage_Electronics_R2&hash=item43b71ec4ca

 

They come out of the sockets with the tubes still attached but atleast the tubes are taller so easier to grab and pull out.

My Lyr and Bifrost combo arrives tomorrow. After much thought, I am starting/breaking in withj Bugle Boy 6DJ8s. I can go up several notches from there and lots of steps that may be preceived,  below. I have two styles of S & H CCAs, I have Telfunken 6922 s and CCAs. I have numerous Amperex 6DJ8s and 6922s as well as 7308s, The fun begins after I put about 100 hours on my Schiit stack. 

 

I'm sorry, I almost forgot I have Senn 600 with original Cardas wires and a new set of AKG 702s.

what do you think about "Amperex 6922 PQ E88CC Vacuum Tubes USA 6DJ8 E188CC 7308|, for which I am bidding?

Is it good for He-5le?

 

 

I love my Amperexes, I think that so long as those tubes are in good shape, you're gonna like em!  

 

I can understand why you wouldn't want to post a link to the auction, one of these bastids will likely try to snipe you!  eek.gif

 

But can you paste the description here?  Are they NOS?

That to me sounds like an excellent plan!  beerchug.gif

I don't know there is no indication of NOS.

What does NOS mean?

I have no idea that auction item is right for me or not.confused_face_2.gif

New Old Stock

post #6052 of 8735

NOS means that Stock is a collection of past production, which had been out of production?

It is confusing..confused_face_2.gif

post #6053 of 8735

NOS is what you really want, but used tubes can work really well also.

 

As Radioking59 said, NOS means New Old Stock.  This means that the tubes are new, never been used, but that they were made a while ago.  In some cases, a LONG time ago.

 

The problem with buying used tubes is that you really have no way of knowing how many hours they've been used.  And when you're shelling out significant dollars, that's at least a medium risk.

 

But bear in mind, eBay can be a risky place for tube hunters in general.  There are people out there who know that guys like us want NOS tubes, so they use that buzzword to jack up their prices, and sell used tubes, or newly made tubes that they fake to look like old tubes.  So go with a reputable seller, and read the seller's feedback.

Thank you very much for the useful information.

Newly made ones can be of low quality even though they can use the same tools to produce, the tool set can not be maintained in good condition due to a long-been dead time?

I'm new to tubes too. I found this. The author seems to know what he is talking about.

Well, there are a lot of theories about why tubes from the old days are better, but precious few hard facts.

 

Remember, back in the day tubes weren't a luxury, transistors were still not as common place.  They hadn't taken over, and integrated circuits were still just a twinkle in the eyes of engineers with pocket protectors and slide rules.

 

So tubes were being made by the millions by big factories.  Naturally people got really good at making tubes.  

 

Today people are still making tubes, but not nearly as many.  And some of the secrets of the tube masters seem to have died with them.

 

But modern day tubes aren't horrible, some of them are quite good.  But crazy audiophiles like us don't really want "quite good", we want the magic!  That's why we look for the tubes made by the tube masters.  beerchug.gif

They weren't hard to find.

 

"Tested on my TV7 with a min of 50, One tested 78/74 The other 78/78 Sold as is, no returns."

 

So, not NOS. But testing "ok". They will likely go for somewhere around $125-175 or more. NOS in this class around $200-250, or Buy It Now NOS for the crazy price of $350. The majority of bidding will occur in the last 2-3 seconds by snipers.

 

Joong, this is a large jump for a first purchase if your not certain.  There is a distinct lack of photos in that posting.

 

Proper listings should show all the angles like this one:

http://www.ebay.ca/itm/2-New-CCa-E88CC-6922-CV2492-Mullard-tube-valve-1970s-tested-/230954886931?pt=Vintage_Electronics_R2&hash=item35c5fbe713

 

From that listing I can see the dimple getter, the pins, and all of the internals. With gold pins its easy to see wear and pictures can tell a story there.

 

Then again, the Amperex PQ white shield is getting rare and listings are of random quality as a result. Good luck! :)
