construction - Black Plate

 

i'm guessing those are indeed NOS levels like their site says? i don't know much about testing tubes or reading tube test results. i'm a happy guy with the 5998 aside from being a little bit concerned about the test sticker result

 

I really don't like vacuumtubes.net at all.  They push off crap as "tested and certified" more often than I can to experience ever again.  They'll never get another dollar from me.

I bought 5998's from them also. They are very micro-phonic but i couldn't be bothered sending them back because i live in Ireland.

I have found TC tubes to be good not only do they use  a Amplitrex AT1000 they even test for excessive noise and microphonics with OTL headphone amplifiers like the Crack. I brought some nos TS 5998's for $75 each with free shipping to the UK!

Back when 5998s were still listed at $25 on their website, I bought 4 of them.  Suddenly, their price went to to $40 in their confirmation emails.  3 of the 4 tubes were rubbish when they arrived, and when I tried to send them back, they said it was my amp at fault.  I finally complained enough and they took the 3 tubes back.  

 

Very unstrustworthy folks.

frank1 also said that they were dodgy to deal with at times. I will look elsewhere in future.

I would advice you to contact them ,I recently received very similar tested tube and I'm getting replacement

My apologies in that a tube that tests that low should never have been sent out in the first place. I will have to have a long talk with my audio tech about his work. The returned tube checked out on our Amplitrex AT1000 tester at:
 
Side 1    73% emission, 84% gm    Side 2    65% emission, 86% gm
 
A replacement Tung-Sol 5998 will be going out in todays mail. The readings on the AT1000 are as follows.
 
Side 1    117% emission, 107% gm    Side 2    104% emission, 102% gm

thanks spacequeen7. i sent them an e-mail asking for a 5998 replacement with higher test ratings and used this thread (and your post) as a reference in my e-mail. now i wait to see how they will reply tomorrow. i mean their site says they store NOS and factory-new tubes. i knew the test results looked concerning and your post only confirmed my suspicion.

My experience with vacuumtubes.net has been... varied. They obviously are more of a generic tube seller than one particularly concerned with audio performance. While they measure them, they don't seem to do any matching or actual listening. But OK, the prices are competitive for an actual retail site (as opposed to some dodgy fleabay sellers) I got some good 5998s through them, but also one that had pops & crackle on warmup, and another with a slight hiss, but I accept that; such are the vagaries of NOS tubes.

 

However more recently I ordered some 12AX7s, 3 incl. one spare: one was fine, one had a bit of hum but was at least working (the usual NOS gamble) but the third one was DOA, no visible physical damage, no problem with the getter material, just no current flow (or glow) when inserted into the amp (no problem with other tubes in the same socket)

 

I emailed them, explaining that I can live with the humming one but at least I'd like them to do something about the DOA one and they never even bothered to reply... So though you may pay a premium on some other sites that do actual testing and matching, it may work out better in the long run...

Can anyone identify this tube?

I wonder if its a 6082?  6080 and 6082 are very similar looking at a glance.  I don't have any personal experience with the 6082, and I cant post pictures... I just saw them on the shelf at a local surplus/vintage electronic parts store about a week ago.  Theres always a certain element of "plug and pray" with used/NOS tubes... Good Luck in your search!!
