Project Sunrise/PS2 Tube Rolling Thread (and maybe even Project Horizon and Project Ember) - Page 25

post #361 of 370

I also would say the 12at7 Telefunken is my favorite tube with the Ember.  I had been using a Mullard cv4024 for a few months and really liked it, but kept hearing good things about the Telefunken so I bought a couple of used ones, that while good were not up to the Mullard.  Listening to the two Telefunkens switching back and forth over a few weeks got to know the difference between the two and decided they may have been used up.  Do I bought a nos and what a difference.  Vocals especially female are fantastic.  Listening to Patricia Barber right now and it is mesmerizing.  Think I am done rolling for awhile.  If it gets better then this I would be amazed.

Well I am amazed got an RCA 12ax7 (actually a Mullard built) and now I am really confused.  I thought the Telefunken had all I needed I just did not know I needed this tube. Just a little better than the Telefunken and CV's but easy to tell it is better.  Firms up the bass on the Ember a bit, less muddy.  Mids and highs are great also.

Let's see if we can re-awaken this thread with something new. I have ordered a 12AU7 to 7193 adapter that Frans of Garage1217 says will work in the amps that have manual voltage selection.

 

That means that Sunrise, Starlight and Horizon could jump to running 7193 tubes (getting a lot of attention on the Ember tube rolling thread) without having to enlarge the hole in the top plate and bypassing the 6SN7 adapter between the socket and 7193 adapter.

 

More to come after I receive and test it.

You're missing the point--the idea is to end tube rolling on the other amps

I am quite interested in your results. I have a couple of the Sunrise III Model. Care to share where you ordered the adapter from?

the Ember with 7193 kill tubes rolling on all amp including him for me :atsmile: the jump from other tubes to 7193 is great ( perhaps the shanguang tube is equal to 7193 tubes) so great why tube rolling? put my money elsewhere....I advise all to put 7193 tubes  and enjoy Ember...and put money on a better cable, dac, headphones etc.....i had put more money on search of tubes than to buying the ember himself... Nobody said to me in the beginning the 7193 tubes are one of the best of the best.... i change tube for discovering the better one in bass , highs, and soundstage.... I read hundred hours of experience on mutiple audio thread all around the internet and the revelation was confirmed when i read the impression of some people who made their own amp and all had the same impressions: 7193 was better than 6sn7, as for me the 6sn7 was already better than all my others tubes, i concluded that the 7193 was one of the top....experience confirm that for me ...end of story for me... best regards :smile:

I just got my Project Sunrise 3.1 and AKG K7XX a few days ago. I do enjoy tweaking things, so I already have an assortment of tubes to go through. I got them all for pretty cheap. Not sure what's special or not. I can provide a list if anyone is interested. I'm new to this whole hi-fi thing, so forgive me if my assessments are simplistic.

 

First up: a US-made GE 6SL7, with shiny (nickel) plates. Tested 400/400 on a Hickok 580, so probably close to the end of its useful life. Very clear with nice separation. The bass takes a backseat to the highs, this is on the brighter side, but not excessively so. It's a nice tube overall. The plates look cool. However, this tube is a bit microphonic. I also couldn't get the bias lowered on the right channel, so I bypassed the input caps, which makes the microphone effect more noticeable.

More tube reviews from a t00b n00b!

 

First, a NOS Raytheon (Japanese-made- possibly Toshiba?) 12AT7. Well, I can't really tell you how it sounds, because "holy microphonics, Batman! This thing has some nasty hum." I'm guessing it's vibration-based, because it was somewhat damped when I put my hand on the PS3.1. But nothing I did really made the hum go away, like moving it as far away from other electronics as possible, or putting a mousepad underneath it to maybe dampen it. None of my other tubes are nearly as bad, nonal or octal. Maybe I just got a dud...

 

Another Raytheon product, a 6SN7GTB (2500/2500, top getter), was next in the queue. I had some hopes for this one - I've read GTB's aren't very good sonically, but the Raytheon might be surprisingly decent. Sadly, it wasn't. The bass is punchy, but the mids and highs are muted. Clear, not muddy, but very dull. This tube did nothing for me.

 

The next tube was a yawner too, a GE 12AT7 (2500/2100, square getter). This one is somewhat like the GE 6SL7 in that it leans toward the bright side of the spectrum, but mids and highs were more like the Raytheon GTB - clear, well separated, but flat. Another tube that does nothing wrong, but nothing right either.

 

Finally, for now, I plugged in a Motorola-branded Tung-Sol mouse ear tube (2300/2300, gray plates). Awww yissssss, now we're getting somewhere! Maybe not super detailed, but detailed enough. These sound airy and wide. Vocals sound really good, just enough bass to keep things thumping but not overwhelming. Very spacious. I have some more tubes to go through, but I'm digging this one.

I just picked up about 300-400 assorted tubes and a EMC 213 tester for $40 this morning. There's a metric butt-ton of common 12AT7s, 12AU7s, and various TV tubes I can't use, but there is also a good amount of fun stuff to try in my PS3.1. I'd say the picks of the litter are three good-testing JAN tubes (Sylvania brown base 6SN7WGT, Tung-Sol brown base 6SN7WGTA, Tung-Sol 6SU7GTY) and a bunch of 12BH7s and 6CG7s (no 6FQ7s among the lot, surprisingly).
