Schiit Lyr - The tube rolling thread - Page 421  

post #6301 of 8735

I am wondering if there is a tube that livens up the treble, airiness, soundstage, and sparkle of the LCD-2s without mucking up the rest of the sound spectrum. Maybe this is a lot to ask, I'm not sure though.

The Amperex USN-CEP 6922's are very very good in the Lyr - some of my favorite tubes.

Sounding thinner than Bugle boy 6DJ8 and GE stock tubes.

 

What is the nature of the popcorn sound?

When I changed to Bugle boy 6DJ8, it is disappear.

 

 

If you changed the tubes around, did the noise switch channels?

I shamelessly re-sold my Lorenz PCC88's on ebay for a profit, but it was all in the name of further tube rolling.

 

Not sure what to buy next.

I've ordered a pair of those, looking forward to see how they sound. What are your impressions on their sound signature? and do they sound nice and expansive?

 

Other tubes i've got on order...

 

Phillips ECC189, Made in Holland for the British military.

I love these valves.

La Radiotechniques E188CC

 

E188CC Buy it Now $120

 

They have Mullard Mitcham "2" codes.  That could be 62 or 72. I could not see the getter.

I bought them from Olga in Lithuania.  I have purchased from her before, as have a handful of other "Rollers"

The product will take a month to arrive.  My PCC88's took 6 weeks, but I hung in there.

 

If they are 62's they are a steal.  If they are 72's they are still a good value.

 

The RTC's I have now are 65's Large "O" made in Heerlen Netherlands.

Can't say enough good things about them.

Gustav,

That user must have known his ****.

I asked the seller for a photo of the getter.

1960's "O" made in Holland getters are getting $250-$300

 

I did find a post from HK with data from Tubemonger that said a big batch of these RTC / Mullards hit the market in Europe and that they were newer.  I suspect these are those because they are white box.  But in the photo they look older / different than the other RTC/Mullards photos.  Darker hat different ink.   The other RTC Mullards look like they were made yesterday.  I'm hoping.

 

Either way, I'm talking about a gold pin, 6922 CCa grade valve for $130 including shipping.  At least $50 under market.  IMO... IMO...IMO

I found that they have lifelike mids and do wonderful on female vocals and acoustic guitar. They are not bright and forward, but rather seem a bit gentle in presentation of detail. Soundstage at first was very compressed in my WA3. The set I received was new and in what appeared to be unopened crisp boxes. They evolved quickly and soundstage opened substantially over the first couple 4 hour listening sessions. I put them far above JAN Sylvania 6BQ7A and better in soundstage than 6N1P. To me, they sound deeper than they are wide or tall. I happen to like deep, which is what also attracts me to the Amperex orange labels. The tubes are dead black silent in my amp.

I'm quite familiar with the 6N1P (Voshkod), would love that tube if it had better mids.

 

The presentation you describe sounds like the 6N1P-VI tubes that Schiit supplies, which would be great tubes if they had better soundstage.

What's a good price for Amperex orange globes? What is the most desirable getter and year? I have no idea what I'm looking for.

Ah, my 6N1P are 6N1P-EV with the rocket logo. Anyone ever try the 6N5P?

6N1P-EV is basically the long-life version of standard 6N1P, the main thing is you got the rocket logos on there, tubes made in the Voshkod Kaluga plant are highly regarded amongst the Soviet tubes.

 

6N5P is pretty much the Soviet equivalent of 6CG7/6FQ7, Schiit said they will work in the Lyr but they don't consider them to be the best tube type. They are really cheap though so won't hurt to try a load and see for yourself.
