Schiit Lyr Tube Rollers - Page 630

post #9436 of 9883

Been eyeballing this set for weeks, tbh do not know what the difference is with the earlier Heelen like my 1966 Miniwatts but this price is pretty decent imo.

I have had no problems with the relay pop when the Lyr powers up. I also leave the hp's plugged in so far without any negative consequence. 


To confirm, you're hearing the low level pops I'm referring to, but they are not causing you any issues, correct?

 

To be safe, I think I'm going to wait to plug in my HP until after turn-on settles (~30 sec), and unplug first before powering down.  I never hear any pops if I follow that sequence.

I could hear that pop even when the headphones are hanging on the wall.

Worries me and not great to hear whilst wearing them.

So when turning on I wait the 20 seconds before the muting relay clicks on before plugging in and unplug before switching off.

Unless you're using a transformer coupled amp, I wouldn't turn on/off any amplifier with the headphones plugged in. It's just good practice to avoid any kind of voltage going to the drivers during power up and shutdown.

Another recommended practice for amps using tubes is to give the tubes at least 2-3 minutes warm up and stabilization time before putting them through their paces. I personally give mine at least 10-15 minutes as I can hear the glass on my big Russian tubes expanding and making noises. (These are 6C33-C power tubes...)

There is an old tube best practices book that I was going to link to... It also says that tube testers put strain on tubes, so it recommends avoiding them unless you absolutely need to test the tubes. Just some food for thought.

Decided to keep the tubes foe now, no longer for sale.

The set of Siemens E188CC that came in the destroyed box via USPS that I posted a pic of a couple pages back just hit 100 hours of burn in, going to give it another 100 hours. Sounds fantastic.

I am not even on the 50 hours with the stock tubes for the Lyr 2. So far it sounds to dark-ish/hollow/muddy a bit harsch even for my taste.Not ideal for all genre's. Vocals are spot on though and especially unplugged stuff sounds really well. Metal etc is still a bit to hollow/dark-ish/harsch/muddy.  
I hope that they open up when I hit the +100 hours. Else I might consider looking for other tubes. Might be my low impedance Shure SRH1840 too (think it is 65 ohm).

Just curious- how do people keep track of listening hours.  Keep a log? I've seen numerous recommendations to not judge a tube until you've listened 50 hours to it.  I recently got a Schiit tube amp (Valhalla) and have been enjoying it immensely but would only have the vaguest idea how many hours I've actually listened so far.

I use a simple text file log, as I'm no Excel wiz (I know @billerb1 must be shocked! ;-).  Looks like this, with other things noted here and there.

 

1966 Heerlen "Philips Miniwatt" E188CCs
---------------------------------------
[VR7 : DELTA 6E2 & DELTA 6G2]

Began Thurs. 2016.04.07
07th: E188CCs 2 hours / HE-560s 2 hours
08th: E188CCs 8.5 hours / HE-560s 8.5 hours
09th: E188CCs 10 hours / HE-560s 10 hours

....

16th: E188CCs @ 3 PM / HE-560s @ 3 PM [for an active session]

 

 

Even with a lot of pairs it's quite manageable.  Schiit happens (e.g., forget to change the start time to the run time for a session), but it gives me a rough idea of how many hours I've put on tubes and cans.  Once you develop the habit of filling it in at the start and finish, it becomes fairly automatic.

 

HTH.

Thanks! I'll give this a try and see if I can get into the habit.

Wow, that is dedication.  I would have to add the hours when I forget to turn the amp off. 

 

Initial burn in hours is about the only thing I keep track.  Generally that has been when I receive them.  I burn them in and they are ready for everyday use.

 

Thuston what tubes do have the most hours?  Any of them near the 5000 or 10,000 hour lifespan?

This is not dedication.  This is mental illness.  But the illness is what allows him to "see".
