Valhalla Problems! Someone Help!  

post #1 of 104
Thread Starter 

Hello everyone, I just recently purchased a Schiit Valhalla on the FS forums a few days ago and noticed only the right side of my headphone works when I use the Valhalla. The headphone is a brand new Sennheiser HD650, and the same problem happens when I hook up my Sony MDR-V6's to the Valhalla. If I run the headphones straight to my Fiio DAC or straight to the PC/Macbook Pro I don't have any problems. I suspect the Valhalla is the problem. I have already emailed the seller but want to ask if anyone knows a fix to this issue! I do have a soldering iron and possess basic soldering skills. 

 

 

Thank you,

 

 

Thomas

 

PS: Anyone that replies to this thread, god bless you, I really appreciate the help! I've freaking out here!

Well vamp, I don't own the Valhalla, but have a couple tube amps.  Normally with channel imbalance with tubes, a tube is the culprit.  Have you tried swapping the tubes from left to right.  If the problem follows, the tube is your problem.

I'll try that now, thank you so much for the reply! Umm when you say move the tube do you mean take the two bigger tubes and move them places or the little tubes? I'm sorry if I'm a tube amp idiot but I don't really now what to do! I'm flipping out!

Try switching the tubes around, one pair at a time to help isolate the issue.

 

nvm, Heatfan beat me to it!

I moved the tubes around and the left side still won't work. I went in windows settings and Reltik audio settings and set to left only and I had to turn the nob to like 5pm (the whole other side) before I heard a faint sound in the left. It was faint and quiet.

Should I unscrew the Valhalla and take some photos of the insides for you guys? Perhaps that might help?! Not quite sure what to do!!!

Have you tried switching out the interconnect cable between the Valhalla and your DAC, just to make sure that's not the issue? If that doesn't help you may have a broken Valhalla.

Wait do you mean swap out the current tubes with new ones? I don't have any other tubes than the ones the seller (Gloomfire) gave me. Do I need to buy new tubes? All I did was move the tubes (2 big tubes and 2 littler ones) from each place and put in each others socket. 

 

I am really sorry if I'm a idiot but I'm not too familiar with tube amps.

No worries sir, switch the little ones first from left to right.  Leave the big ones.  try one thing at a time to isolate ...Leave the big and little ones in their respective sockets.  Just swap them from left to right.

Hey I did change out the interconnects, but I'm still having the same problem.

If you switched both pairs around and nothing has changed, it sounds like you have eliminated the tubes as the culprits. You switched them right to left, not front to back, correct?

 

Like Heatfan I don't have a Valhalla so I don't even know if front/back is a possibility, but I kind of doubt it because they are different tubes.

I didn't switch front to back lol they are different sizes. I just switched the little ones front left to right and now I will try the big ones.

Wait a minute. Is it possible the tubes are broken from shipping? The little white thing inside the tubes (the white thing that has pins on it that glow) is kinda bent and kinda smoked/dirty. Hard to explain will post pictures!

Turn off the lights and see if they all glow, but switching them from left to right will be the most definitive. If there's one bad tube, the lack of sound should follow it to the other side when you switch it with the good tube.

Sounds like a bad tube g....
