IMO, it is very unlikely you damaged both valves in one day by handling them wrong.  They are more durable than you think and a little tap can actually clear up some static issues.  

 

Please clarify what you are saying.... you rotated the valves and now both channels have noise?

 

If you went from one bad channel to two bad channels after rolling I would hold off installing the OG's in the unlikely event that your Lyr is damaging the valves that were placed in the one socket.

Hence one valve get's corrupted, it is moved to another socket, and the replacement valve get's corrupted.  I haven't heard of this happening, but it's electronics and anything can happen.

 

If Schiit doesn't send you new factory valves, I will.  I only use my stock valves for testing.

My fear is that maybe I applied too much pressure? The tubes, like I said, do not feel as though they are secured at all. They light up and when the volume is up, you can't hear anything. But it is certainly not dead silent. This is mainly from the right channel. I hear it more with my Sig Pros than the LCD's. The word 'ting' definitely explains it. Who knows, after work it might be fine. Crazier things have happened.

 I'm guessing, after speaking with Jason, that I'm just not pushing them down hard enough. I was very worried about breaking them. We'll see when I get home. Thanks for the input though.

There's a real "feel" to working with them.

They can take more abuse than you think.

 

How I would approach it is to remove them, examine the pins and start again.

 

Removal without tube extenders can be a bit of a pain.  Firmly pinch the crown of the tube with your fingertips.  Gently rock back and forth an 18th to 1/4" inch side to side and back and forth, while trying to apply upward, extraction pressure with your fingertips.  This can take some time. It can be frustrating too.  Do a bit.  then take a break and resume.  The tube will come out.

 

Reverse the process to insert the tube, except with minimal rocking.  "Light-Medium" pressure should put seat them nicely.  Pay careful attention to the 9 pin socket.  The tube can only be aligned one way to go in.  You may hear a squeak / creak sound when you push the tube in.  That's normal.   Also look at the picture of the Lyr.  This will give you an idea what the Lyr should look like with the tubes fully seated on the socket.

 

Hoping for the best.

 

Jason,  If you are reading, perhaps you should put together a Youtube video on this topic.

 Here's how it looked last night:

 

 

 Looks way too high. Hope I didn't damage anything...

post #5421 of 8735
Indeed.

The good news is they would not light up if the pin orientation is wrong.
Pins 4 & 5 are the heater pins. They are working.
Might just be that the anode, grid, cathode pins are not secure resulting an unstable contact and noise.

Purely conjecture on my part.
They certainly look a bit high.

If you can easily extract the tubes than they were not seated well. Because when the tube is seated correctly it's difficult tor remove.

They do look a bit high, but which tubes are you using?

post #5423 of 8735

TooPoor, here's a tip or two...

 

Install the "rear" tube first. That way you can watch the insertion thru the empty hole for the "front" tube.

 

When inserting a tube, push firmly enough to fully insert the pins until the base of the tube makes full contact with the white tube socket.

 

Is that clear as mud? smile.gif

 I'm completely conflicted at this point in my head-fi journey. Should I be buying thousands of dollars worth of head-fi gear if I can't properly insert a tube?? Sarcasm aside, I very much appreciate everyone's input. I'm still new to this all (relatively speaking).

It's fine... not life or death.

When inserting a tube here's how I do it...

1. Rubber glove (the one you proctologist uses but make sure it's fresh, not used).

2. Flashlight in the other hand (visibility is key).

3. With the flashlight on, line up the tube with the corresponding holes in the amp - line up the two pins with the gap between them with the gap in the amp.

4. Gently but firmly Push down whilst very very slightly wiggling left/right.

5. Check that it's all the way in (get your mind out of the gutter).

6. Turn on amp.

7. Wait 5 minutes.

8. Sit back and listen. Enjoy the music.

Old Skool & Eddie,

More good tips.

 

I have to post a plug for one of my top five tools.  Get A HEADLAMP.   It will change your life.  Home Depot / Costco have 3 packs.

Everyone... Just buy one.

 

TooPoor.

This isn't a concern with your stock tubes, but when your vintage stuff comes in be careful with the labels, the printing is fragile.

Hmmm. You mean a headlamp that attaches to the bill of your cap, or the kind that miners wear on their hard hats? wink.gif

 

I may just drop this hobby if we need to start wearing protective headgear. biggrin.gif

Pelz is a great brand.  IMO

This is a low cost version, but highly rated.

You can get some amazing models.

You won't know what you did without one.

Kind of off-topic, more related to mods ... All my old guitar tube amps have/had a standby switch to make it safe(r) to unplug/plug your instrument in without damaging anything. The sequence is always standby on -> amp on -> plug in -> wait 30 seconds -> standby off -> rock out -> standby on -> amp off -> unplug. How hard would it be to implement this on the Lyr?

Because of those persistent rumors about turning the Lyr on/off with headphones plugged in I always turn the volume down and then plug/unplug. However, there is still an unpleasant, albeit low crackle and I'm concerned I'm damaging my drivers. Maybe this is a myth and has been debunked so let me know if I'm on the wrong track with this line of thought.

Also, found this earlier today if anyone wants to read an old 60s manual on the care and feeding if your vacuum tubes: http://www.nutshellhifi.com/library/MostVacuumTubes.pdf

Hey Iamnothim, where did you get the bumpers in your picture? I'm assuming those are vibration dampers of some kind? What do they do exactly?
