Awwww i just got my tubes from surplus sales and i got 10 GE 6BZ7's
*is very sad now

 
 
Sorry dude.  I hope I didn't get all the RCAs.  I guess that's the risk you take when placing an order like that at a surplus seller like that.
 
But the good news is that you got them for $1.60 each while Schiit is selling them for $10 per...  Can you make out any date codes?  They may very well be NOS tubes.  As far as I can tell the RCAs I got were made in '67...

They look good, Matt! They should also sound especially nice with the HD650

 
Look near the bottom for a date code that begins with a delta. It looks like a right-sided triangle. The next number after the delta should be the year it was made.
 
IMO, the A-frame construction usually results in a quieter tube. Also, I have NEVER seen a counterfeit Amperex A-frame.

 
Thanks!!

I guess it was a decent purchase excluding the whole shipping amount i had to deal with. I'll have to go home and double check the date, i was pretty sure they were NOS. Sadly looking at the internals was very discouraging because their halos werent perfectly aligned / some of the internals were tilted. - And i doubt these attributes would be considered "good grade market tubes"

I wouldn't worry all that much about that, the Amperexes I'm using right now don't look all that well aligned either.  How they sound will be the real acid test.

Hi guys,
 
Could you tell me that PCC88 7DJ8 NOS LORENZ SEL TUBES are good choice for HE-5LEs or 400s?

 

[toschek]

The SEL PCC88s have a very nice, open top end but the bass is a little lean as is the midrange. It depends on what sound you're aiming for. I have a set I can sell you cheaper than eBay, as I bought two from the same seller you're probably looking at. I liked them a lot with the Senn HD700s I used to own, but I find they are not a good match to the HD800s I have now so I'm going to sell them anyway. PM if interested.

I disagree. Sure their a bit lighter weighted, but you can actually begin to hear detail with them. Nothing else in my little collection has gotten me there with the 800s/Lyr. As is everything with the Lyr/800s... it comes down the recording. The bass has to be there, or it won't be.

Toschek,
 
How are your Telefunken vs the Amperex?

 

[toschek]

The Telefunken tubes are phenomenally detailed and spacious. Probably the most balanced and neutral of all the tubes I have for the Lyr too. They are really spendy though. I haven't heard Siemens Gray Shield CCa tubes, but I'm told they are pretty close only maybe a notch more forward.

They don't just sound good with HD800s, they mate with them. If you like what the Lorenz do for detail with your headphones, then you'd love the 6922s. But for like 10x more $ you'd better.

I own HE5-LE's and have ordered a set of these tubes, will post my impressions when i get them, but waiting for burn-in might take a while.
 
Out of the tubes i have so far (GE 6BZ7, RCA 6BQ7A and OTK marked 6N1P-EV) i must say the GE 6BZ7's have the best affinity with the HE5-LE's, the other tubes seem to kill off the sparkle in the treble, 6BZ7's seem a far more balanced and more detailed tube.

Hey guys, I just got a used Lyr that I am going to be comparing with the Asgaard 2 when it arrives in a month. It came with a number of tubes including Lorenz, Mullard and Amperex White Label along with the stock JJ's. I am using it with HD700's and all are giving me a low level hum when the volume is turned down. The quietest are the JJ's. BTW this is definitely not environmentally induced as it occurs without a source input and with or without the third pin. My question is - do any of you have recommendations for particularly low noise ones?

I really enjoy the sound otherwise but am concerned that this may be a design limitation given the efficiency of my 700's. I have exchanged emails with Jason, and he states that the tubes are after the volume control and that he would expect to hear differences in hum level. He also mentioned that the JJ's are some of the quietest tubes though lack other qualities.

Can 6CG7/6FQ7 be rolled into the Lyr?
 
Only thing i know is that they draw more filament current than a 6DJ8 but they seem pretty abundant on ebay, far cheaper that ECC88 and other tubes people have been talking about on here.
 
*EDIT* got the answer from Schiit
 
 
Quick reply!
 
So not that good, but at the price point they're being sold for, it's gotta be worth trying some, right?

There was a run in the thread for a while of a lot of folks (including me) using them in the Lyr.  Several folks were quite fond if the sound.  Do a search within the thread and you'll find what I am talking about.
Hope this helps...
 
Cheers!

These really have to be burned in a while for all their qualities to show.  Give them time and you may be pleasantly surprised...

Please!  Do NOT go into details on that comment!

  Seriously though, Telefunkens are known to be a drier, more analytical tube than the Siemens and have been described in the past as the closest thing to a solid state sound in a tube.  I've heard (I don't own one) the HD800s are very analytical as well.  So if you pair (or mate...

) them, there won't be any sense of warmth.  Hope that helps...
 
Cheers!
