Hi All,
I have recently purchased an Atlantic dac with preamp, super clocks, tube rectification and remote volume control.
I don't see a thread that is for this preamp version so I thought I would start one. I also have a couple of questions.
I recently received some rectifier tubes that I purchased on ebay after reading a discussion that said they can change the sound of the Atlantic. Since I know the other tubes can't be changed I thought I would give it a go. I also think I read that you can replace the rectifier tube without turning off the dac. Does anyone know if this is true?
I'm also curious about what amplifiers people are using with this configuration of the Atlantic? I read in the installation instructions from Lukanz that he doesn't like class D but have not read any recommendations about what people do like.
Thank you for any input you may have.
Greg

Hi, Greg.
I can't wait to try it out with my D Sachs Kootenay 120 and Model 2 pre....perhaps in February?? :drool:
-
I use Melody 845 mono amps and RCA crc-5r4-gy tube with the Atlantic.
-
Same unit on order...to be used with a Wells Innamorata Signature. As long as your amp is a good match to your speakers, you’re good.
-
Thanks guys!
Michael, I'm super exited to hear your wonderful new amp and preamp. I'm also very interested to hear how your amp will sound with my Lampi.
February sounds great!
findog3103 and anyone else who posts the tube they are using, could you give your opinion on it and the difference compared to the stock tube that comes with the dac? How does the Melody do in adding warmth to the presention? I'm definitely leaning towards a tube amp.
jriggy, you are going to love the Lampi. It is so transparent and the depth into the music is something I have not experienced before.
Greg
Sorry, responded late at night.

Yes, I know! I had an audition. And coming from and L4G4 I was happy it kept certain qualities and built on them, as well as improved upon that model.
I also have an RCA 5R4GY in waiting. They were made in the 40’s all the way through the 60’s, with slight internal difference along the way, so I didn’t know what year(s) to look for.
-
I would turn the dac off when changing the rectifier tube. Electronics and voltage spikes are not friendly. Even a small spike can do damage, IMO.
-
Greg, e stock tube is great but I feel the NOS adds a little more clarity. Hard to tell but for a pair of those NOS on eBay for $50 I felt I couldn't lose.
The Melody amps, imo, aren't typically tube amps. They rock hard and slam when they need to. Still, I like the natural texture they evoke compared to some solid state and other tube amps I have used. I don't think there's too much credit location in my system but I'm biased. It's mine. If you're ever in Philly, you can listen for yourself.

It must be pre-1946, ie WW2 version.

No need at all...however, as a precaution, I turn the volume down completely, but its not even necessary.

Hi Jason,
the double Mica 5r4gy is the killer. Stay away from Fivre and Marconi as they are waaay overpriced. Haltron /CEI/Zaerix/Mazda/Brimar are all available for decent money and can be had for cheap. In the GG, with certain tubes the Shuagang 274B is very good and for big money, the Lampi Kron 5u4G is very hard to beat.
Finally, try the potato mashers.. they are 5r4gwa, gwb and gy
-
Hi Wisnon,
Seems I have the one made for Marconi, but I got it rather cheaply. Tried to find a double Mica 5r4gy but hard to tell on eBay. Any hints how to find it? Also, the stock lampi has no identification: any idea what it is?
Here is my vintage tube, can you tell which one I have?

I just received a Chatham JAN CAHG 5R4WGA, your part number is slightly different "gwa"? Is this a typo or are there both types?
Also, how do I tell what year they were made? I don't see a date, only that it was made in the USA.
As you can tell I'm pretty new to tubes...
-
I'm agree, Greg, tube identification is challenging. I'm having a hard time understanding and finding double mica and ceramic top.
-
Hi Jason, you need to take a picture of the very top. You cut off the very section I need to see. The Mica is the plates on top and the one we want has a ceramic spacer between the 2 plates.RCA didnt sell the double Micas, only Ultron/Certron/Haltron/CEI/Fivre/Marconi/Brimar/Mazda and maybe TC.
Pictures and discussions hre: https://www.audioasylum.com/cgi/vt.mpl?f=tubes&m=248880&VT=T
For RCA, just google the identification codes online. From memory, H5E is 1944.

I have no year feedback about the Chatams...so not sure that makes a difference.... Please reread my PM where I explained that there are many suffixes to this potato masher tube. In thi case, its probably a Typo that I made though.

They jacked up the price on this one, but its still worth it! Vivatubes.com

Thanks Wisnon.
Here's a photo of the top though I realize it's not a double mica.

Thanks for the info. I was in Philly once a few years ago. Growing up in Seattle it was wonderful to see all of the old brick buildings. The area we had lunch which I don't recall now had all of the restaurants bringing tables out daily onto the brick road in front of them. Very festive for sure. Thank you for the offer, if I end up there again I will try to contact you.

1945 RCA 5r4gy WW2 construction.

Snagged... thanks wisnon!

Snagged... thanks wisnon!
jriggy,
glad you got a hold of this, let us know what your thoughts are once you've had a change to listen to the stock tube and then to this tube.
I almost bought this yesterday but decided since I just bought 4 different types to play with I could wait for another day.
Wisnon, keep up the good finds. I had a small G2G on Sunday and we did do a very quick swap, not really a serious listen so all I can say is we did hear a difference between the tubes we tried.
-
Guys, Santa came early this year. This UK seller has TEN at half the VivaTubes price...less than $50 delivered!
Run, dont walk and snag one! Thank me later...

Thumbs up! That is the built in fun with tube rolling. Its such a social activity!

I'm listening to one of these right now. Great tube. I've come full circle with it as I've loved it in my Melody integrated when I had a stock Atlantic. After getting superclocks and tube rectification for my Atlantic I thought it was too much of a good thing so to speak. I've got my system in a different room now and have made some adjustments in other areas and this tube just rocks now. I usually get it from Taiwan for about $50 so this is good to see one from the U.K.

Fuuuuuuuuudge (only I didn’t say fudge)... Just saw this post... mine from VivaTubes just arrived today. Crap. And to top it off, I was wiping dust off the tube and the base shifted/turned. So the base turns back and forth on the glass (or vice versa) 1/8 of an inch or so. Maybe they’ll take a return... I can’t test it yet, Atlantic has not shipped yet.

JRiggy,
Did they take it back?

Just saw this! Yes, they did. Double mica has been doing very well. I’m curious to hear the more modern sounding KR recti but I currently am not tempted enough.
And thanks for posting the review. I’m loving mine!
Had a tonality issue at first that worried me it was a bad match/synergy issue. Turns out it was the new to me attached custom metal footers on the unit reacting with the granite shelf of my rack. No other footers I had on hand (three dif kinds/three dif approaches) sounded right to me. I remembered I had some Herbie’s Grungebuster Dots (perfect size), put them between Atlantic’s footers and granite shelf, and boom! Everything locked into place!

Wisnon, thank you for the link.
I had a G2G where we were able to listen to two different Hollo Springs L2 dacs. We compared them to my Atlantic dac which was configured the same as the review unit and pretty much came to the same conclusion as the review.
The L2 is a very good dac and I believe it to be a great value as well.
Wisnon, if you find another good deal on the recti tube you pointed to on this thread before let me know. I'm finally at a point to pursue this again.
