This is interesting....     To follow up - I received my new dt880's from amazon about a month ago, and have had no problems since.  App11s's post scares me though - I don't want this to happen again.     Not sure what to do though - anyone have any advice????

@MilesDavis2:   I use a WA3 with a DT880/600ohm, and love it!  I havent had any experience with a WA6, but I can say for sure that the WA3 sounds good.  Prior to buying my amp I did consult Jack from Woo Audio, and he assured me that the WA3 would drive the Dt880/600 ohm perfectly.  Jack is...

Is it fair to say that a higher quality unit (Marantz CD5004) probably will not have this issue?    

the ground I run from the hardware of the player to the outlet metal undeniably fixes my problem.   I am confused why the problem exists at all.  The dvd player is acting as a transport - does it make sense that RFI can be carried across the digital signal?  Can someone explain this to me?

To follow up on my noise problem.   I took the face plate off the outlet the dvd player was plugged into.  Plugged the DVD player back in.  Touching a bit of speaker wire from the chassis of the dvd player to the metal inside the outlet area totally removes the sound.   Forgive my...

grokit and I discussed via pm that a cheater plug on the amp probably would not help. The system is silent when the source is my soundcard and thus it would mean the amp itself isn't to blame.  however, we decided it was worth a try - but I am sad to say that this did not change anything.    ...

Thanks in advance for those who read this and respond - I really appreciate it.....................................   So I have recently starting trying to move away from computer based audio - I study with a computer all day, plus the internet is too damned distracting.  I'd like to step...

If you guys are lucky enough to have a used cd store in your area, you should check it out.   I, too, have burned cd's from the library, but some cd's should be owned out of respect for the music and the artists themselves!  That said, I am in favor of auditioning, and understand the...

Thanks to everyone here - I appreciate it.  I do believe we have it narrowed down to a faulty can.  Heres the good news!!!!!         Quote:  

Wow.... All I can say is Wow.   thank you first to everyone here and all your advice.  I do believe we had it narrowed down to a bad set of cans - not sure which piece, but anyways....   Thanks secondly to Amazon.com - the second best company I've ever dealt with (just behind Jack and...

I was going to try amazon first, in the morning....   Its just been 5 months, I dont see them doing it... but maybe?  

Yes, I did check source balance - they were set equal.  In fact I've played with it to the point that I detect equality when I put 20% in the left channel (the working one) and 80% in the right (the bad one).  And when I do this and therefore force the right channel to be loud, its very grainy...

Help!!   I am having REALLY reduced volume in my right channel suddenly - and I think I've narrowed it down to being my 5 month old Beyerdynamic dt880 breaking without reason.  I feel like I've done enough to rule out it being the fault of my WA3....but maybe I have not thought of...

  I think my Beyerdynamic dt880/600's are broken!!!!  Basically the right channel is about 25% as loud as the left.  It is noticeable, and was sudden.....     Here is my story....   After rolling a tung Sol 5998 into my Woo Audio 3, I turned on the amp, let it warm up, then sat down...

So I should leave them in awhile and let them run before giving up!   The amp just needs to be on, right?  No music needeth flow?     Anyone else have this issue?    

Does anyone have experience with fleeting hum that shows up initially in NOS tubes?   I have heard whispers of it - that "often" NOS tubes initially have some hum that goes away with time.  Can anyone comment?   I recently got some NOS 6dj8 JAN Sylvania drivers for my WA3 - they hum...

As a full time student (aka, I am broke) and fledgling head-fier, I have to say I am really amazed at the tube collections that have been posted over the last few pages!!!   You guys are truly on a whole different level!  But you can only appreciate where you are when you can look back at...

I am looking for a power tube and am struggling to decide between a 5998 and a sylvania 7236.  Several posts ago it was agreed that the 5998 was a bit noisy.  Is the 7236 by Sylvania equally noisy?   My WA3 (with stock tubes) has some background noise at higher volumes.  Its not even...

Do others have experiences with loud 5998's?   I am about to roll my first new tubes into my WA3, and I was really hoping to get rid of that slightly background hum/noise you hear at high volumes, and was considering the TS 5998.  I don't want to spend the money if its going to get worse...

Does anyone have any experience with the 2399 Chatham?  A rebranded TS 5998 supposedly?   Are they identical, and if not, any differences I need to be aware of?     Its for my WA3.

Both would be awesome, but I am a full time student and money is tight.   Plus, I need to buy more music!  Whats a good setup without the tunes?   Where do you guys (skylab, golf, etc?) get your music?  Download it from hdTracks or the like?  Or just stick to cd's?    

I feel like I learned something on here today!  Thanks all.   I also think I've decided on my tubes for my WA3:   a pair 6DJ8 Sylvania JAN NOS 1971  7236 SYLVANIA NOS 1962   My last decision is between that NOS 7236 and a lightly used TS 5998.... Its nice knowing either way I go...

Can anyone comment on their experiences at tubeworld.com?  Brenden there has been very helpful via email.   If their website says NOS, can I assume it tests well and do not need to ask for test results, etc?

Good info guys, thanks.  I can see myself buying a tube tester sometime down the road.   My final question is this:     Also, what do THESE numbers (the "ma" ones) mean?   1 low noise pair 6DJ8 Sylvania JAN NOS 1971 same date codes 1 tube) 24/26ma 1 tube) 23/26.5ma 1 low...

So is the minimum value something that is determined by the tube tester itself?  Meaning the tube tester in that case had a min value of 40?  Therefore using your 1.5 rule you'd expect the tubes to test 60/60? (40 x 1.5 = 60)     Why do they list the results as 40/40?  why two numbers?  ...
