Schiit Lyr Tube Rollers - Page 458

post #6856 of 10883
I have a short question: how much should I burn tubes in?
I received 71 Voshkods burnt em for about 25hours, and up to now they re no better than stock.
Tried some Reflektors 74 which already have 75hours, and wow !
Do you think the Voshkods will eventually open up or did I get a pair of doozers?

Our Russian tube Guru rb2013 would tell you that the Russian tubes can require as many as 200hrs of burn in.  I have multiple sets of Reflektor and Vokshod's and have found the SQ will change during the burn in period.

 

The 74 Refecktor silver shield SWGP are my 2nd favorite of the Russian tubes.  The only ones I like better are the 75 HG's. 

 

Your are holding the 71's to a pretty high standard compared to the 74's

 

Of course IMHO and YMMV...

Thanks for your answer! Of course I didn't anticipate the Voshkods to hold their ground against the Reflektors.

It's just that, at that point, it's not even funny how much they get crushed (or smothered or obliterated, you choose the adjective biggrin.gif).

I will let them burn every next week ends before I give em another run smily_headphones1.gif

ps : this is based on a very quick run with my newly received HD800 (which seem to be demanding a**es when it comes to amping).

My first set of Russian's were 77 Vokshod gray shield.  After burn in they sounded a lot better than the stock tubes.  So give them some time before you write them off.

Hey guys. Decided to part with my 1966 Siemens CCa "Grey Shield" I got from Brent Jessee, and also my 1969 Mullards from the Blackburn factory. Two totally different tubes, yet fantastic in their own right. Let me know if you're interested.

Hi. I found pair of Philips SQ with code

first:        7LG delta 2a3

second:   7LG delta 9I5

What year it could be?

Is it worth to buy if I have pairs of Orange Globe and Bugle Boy?

First = 3rd Week of January 1972

Second = 5th Week of September 1969

 

Philips SQ as in E88CCs?  Could be worth it, depending on the price.

Hola Thurston. To touch on your post a little, I contacted Brent Jesse regarding my Valvos. The one tube that I assumed was a 72(7LG ◢2G1), is in fact a 62. His reference to why it's a 62 is because of the Grey plates and shields. I didn't think that applied to heerlen tubes, only Siemens. So I guess if they're silver , it's 72. If Grey ,62. Still gets confusing at times. Lol

Well, I've come to the conclusion that (to my ears) the Lyr+ my Valvos , sounds best after about an hour+ of warming up with music being fed through the tubes , during the warm up process. At first I would let my Lyr warm up and get toasty , then start playing music. I noticed that when using that method , things would take a while to get to full potential of awesomeness. So I assumed that the tubes needed some signal running through them a bit before playing any music.
So what I did was start with the old method, play a particular song that I'm very familiar with, and evaluate the song.
Then I shut everything down , waited a few hours , then went with method 2, with both the amp warming up, with music being fed during that hour, then evaluated that same song. It's a night and day difference in sound to me.

Has anyone else tried this? If so , can you confirm that I'm not crazy? LOL

Cheers,
Sam

No your not crazy...

 

I feel the same way.   My system sounds better after a warm-up period.

 

No science just IMHO...
