How did you know, did the Schiit Line Operator tattle on me !

They want you to send it back?

Nuclear? Like what did you see? I've heard tubes can implode

I had thNOS tube in, turned the Lyr on, then when I plugged my headphones in I heard a little pop an smoke.

They want you to send it back?

Yes, so heading home as soon as receive the return authorization.

Yes, so heading home as soon as receive the return authorization.

Let us know what they discover and what comes of it. Hopefully your not away from the amp too long.

I was sitting on the couch one afternoon immersed in musical nirvana and suddenly heard a crackling out of the right speaker. Looked at the amp and the plates for the two right channel 6550 power tubes were bright cherry red. As I jumped up in mortal terror there was a pop, which was the fuse in the amp blowing...thank goodness. Yanked the tubes, replaced the fuse, and everything was OK. That was my first -- and my last -- purchase of Chinese power tubes. I've never seen a tube explode (or implode). I suppose it's possible, although any reasonably well designed amp should have protection for runaway current, either through fuses or resistors (that would fail open).

If you find a sylvania 6sn7wgt buy it! New favorite tube for the lyr3, mines a 1956 with the 3 hole short bottle chrome dome. Looks bad ass in the amp too, almost holographic chrome that looks to extend out of view from the naked eye. The tube is extremely detailed in this amp, it’s hit the perfect amount of oomph in the mids and highs out of all the tubes I’ve tried and also has the most accurate bass and slam. No more tubes for me, found the one.

Given that the lower half of the tube is below the deck that smoke could be from the tube base area and just appeared to come from inside the amp. I've experienced some tube related issues over the years but noise issues aside it was always an implosion or the over heated cherry red plates. It's pretty exciting to hear a tube implode even with the volume at a moderate setting. My brother and I affectionately referred to the process as a "launching". One brand of power amp we owned back in the 80's was notorious for doing this, especially with his Infinity RS1's (I think they were) ribbons.

"I had thNOS tube in, turned the Lyr on, then when I plugged my headphones in I heard a little pop an smoke."

New with the LYR-3; isn't this the first of Schiit's amps that mutes the pre-outs when phones are plugged and vice-versa? Maybe something to do with the auto-mute circuit.

I hear a click/pop, a few seconds after I first turn on my Lyr 3. It scared the crap out of me when I had my headphones on. Is this normal? I thought it was just the tube warming up?

 

[Wes S]

Do you all leave you headphones plugged in, on start up?

 

[Wes S]

My tubes on the Valhalla make noises on startup, but not quite like the lyr 3.

 

[FLTWS]

I always unplug my phones at the end of a listening session with any of my HP amps. With any of my HP amps, tube or SS, I allow them to warm up for 20 to 30 minutes before I plug phones in and start listening.

My LYR-3 is scheduled for delivery Monday per the tracking #.

Do any of you, that already have your lyr 3, notice a click/pop sound a few seconds after the tube is powered on? The tube lights ups and then a couple of seconds pass and it seems like something is building up and then click/pop. Everything seems fine and quite as can be, after the click/pop. I have heard the exact same sound with all the NOS tubes, I have tried, so I don't think it is the tube.

@Wes S , I too get them click/pop. On some days, the pop/click is too loud, while not so loud on the remaining days. But it’s there.

Apparently, there are some amps that require you to have the phones plugged in before turning on and shouldn’t unplug them before turn off. Example: Massdrop CTH

Since I am new to the discrete amplifier, I am not sure what the best practice is. @FLTWS seems to have had extensive experience with amps, and if he is okay with not having the headphone plugged in during start up, I feel confident/comfortable following the same.

I haven't heard this with mine, and in fact I listened for it a number of times when I first got it. No audible indication whatsoever of the mute relay disengaging. I would always hear a very faint pop with the Vali2...not sure if it had a relay or it was just the tube starting to emit, but so far my Lyr is dead silent.

Just got reply back from Schiit. They said it was normal operation of muting relay. Pretty awesome customer service, to respond back in minutes on a Saturday morning! Back to the music
