Bought mine from Kidult @ eBay. Slightly higher price maybe but for EU it`s fast delivery (from UK) and safe to buy. Recommend that seller.

 

Edit: seems this seller is out of business.

Hi CoiL,

 

Thanks for your detailed tube recommendation last time. Please keep us posted about your wooden box project:bigsmile_face:

 

 Few tubes has arrived couple day ago, here are the photos:

(Please ignore the EH 6922 at the back)

The right one has a D-Getter, didn't know that at the time I placed my bid, kind of surprising when it came:p

The Bugle Boy on the left is by far the most "tube sound" amongst all my other tubes as well as the warmest.It condense every single note with pleasant coloration; but soundstage is quite narrow and up front. Guess it would be suitable for Chamber music or jazz.

 

The ECC188 on the right however is very different, soundstage is much wider but slightly flat in response IMO. But I'm not saying it's no good.

 

Telefunken, finally have a chance listening to this legendary brand, since it is a PCC189 without gold pin, I got it at a reasonable price.

Impression? I'd say: "Typical German hi-tech technology":D It gives you everything you need except... passion and emotionality.:rolleyes:

D-getter, nice. It usually means old and rare. My 7DJ8 Tele is probably my most natural sounding tube. I can't notice any major coloration or emphasis with that one. It's also very transparent and has nice bass. All this being said, I kind of agree with your opinion. Tele is high tech high end but can also feel slightly industrial. It's one of my best tubes no doubt, but those Amperex tubes are imo better if you need that extra soul from your tubes ;)

 

BTW does that bugle boy have small, medium or large halo getter. I have one with small halo getter and it's indeed more tubey sounding than, lets say, orange globe for example. Similar but more tubey.

I just had a tube die on my T1. Switched it on and the tube filaments did not light up, the volume was extremely low almost inaudible. The tube also got much hotter than usual even though it was only on for 1-2 minutes.

 

The tube was an Amperex 7308 PQ purchased a few weeks ago from a reputable seller measuring 12.5/12.0 & 12.5/12.0 mA/Gm (nominal new measure 12.0/11.5).

 

Anyone had a similar experience?

post #2975 of 8012

These things happen unfortunately with NOS tubes but ouch about 7308 PQ, expensive tube to die, r.i.p.
But maybe it has "a loose connection" because of shaking or something, like one of my Tungsram PCC88 has, sometimes works sometimes not. 

 

Btw, anyone willing to try this: http://www.ebay.co.uk/itm/ECC189-CV5331-PHILIPS-NOS-BOXED-/310355054686?pt=UK_Sound_Vision_Valves_Vacuum_Tubes&hash=item48429a505e

Amperex 7308 is my favorite tube. Sorry to hear about your loss. I have been using mine for 3 months. I hope it lasts many more!

Good report! Your comments on the Telefunken are interesting. Let us know how these tubes break in as you use them.

Ditto on the TFK PCC189. It's veeery flat and neutral, which ppl would deem emotion-less, but it's what I want since I output into a tube amp that adds it's own color. With the TFK in place, it's very much an Odac but with the added benefit of changing the sound just by switching tubes. smily_headphones1.gif

Has anyone ever compared the DAC section of the Aune to the Tubemagic D2?

Hi Salvatore,

 

Great minds think alike ;) In order to answer your question, here is the photo of my Bugle Boy (cause I don't know how to determine distinction between large and medium:o) Guess it's a large one???

 

Another 2 tubes came this afternoon:D 

Valvo E88CC, A frame with gold pin.

 

Built quality: crap! one of the them the getter totally lean on one side of the glass, pins are bended, scratches on components inside:mad:

Impression: Well, everyone better keep their hands off these crappy rubbish valve whenever you see it on eBay, just call me and I'll handle it:veryevil:

Confession: Excellent! Solid punchy bass, good separation, ENERGETICALLY DYNAMIC and AWFULLY POWERFUL! Sound stage wise is kind of middle spaciousness.

P.S: If spending money on these tubes is considered as a sin (especially in wife's point of view), so be it!:evil:

 

 

BTW, it came with two little packs of gummy bears, yum-yum:popcorn: Highly recommended to every seller should do the same!

The upper wave is the input signal to the Aune and the lower one is what i get as output from it.

 

It looks like the tube only amplify half of the signal (the positive half); the negative one is completely clipped. It is strange that both me and Sarurururu got faulty tubes but this test speaks by itself. It's not all about grid tension, the negative half of the wave is clipped!

Can anyone here owning a 6N1P make a test? So we can definitely say if they work or not with the Aune T1.

 

This is a photo of the tubes.

 

 

Impressive and interesting finding mate! I just ordered lot of 8 pcs of 6N23P

:o

Yes it looks like it's either a large or medium halo. Basically small is so small that you know it when you see it and large is almost as big as fits. Large halos should be the best or at least the most wanted bugle boys. You got a D-getter and (to my eyes) a large halo which is really cool! Many ebay sellers are saying they have large halo but they either really don't have it or they are not showing good enough pictures. Also your prints are in very nice condition. Large halo and good prints like that... well that's one mighty fine collectors item there. Even if it doesn't get as much listening time as some of your other tubes it's still a great iconic piece of tube history.

 

At some point you should put all your tube impressions into one post so I can add them to the T1 info post.

 

For the sake of comparison, here's a picture of my small halo getter.

I wonder how the Bugle Boy sounds compared to the Russian Rocket tube? Thoughts?

Haven't done any straight comparisons but I think my bugle is somewhere between rocket and orange print. I don't remember it to be very forward sounding though so definitely closer to orange. I also think my bugle has been used quite a lot before it came to me, so it might be past it's prime. I bet Saru will post impressions after his 6N23P tubes arrive (assuming they are rockets).

Is the DAC part or the amplifier part of Aune T1 which bright? I found Senn HD600 + Aune T1 to be quite bright. Any though?

What tube and what song? As for me, there is no too bright sound. But maybe because I love bright side than dark side. BTW, using 6922 tube. Haven't try stock tube tho..
