To give you an idea on cost, here are some links...

 

Original Telefunken tubes - very fast, quick decay, "solid state" sounding, with a very natural sounding tube infused sound... not particularly warm or bloomy... good for faster genres like metal/jazz:

http://www.ebay.ca/itm/Telefunken-E88cc-NOS-tube-/201388070918?pt=LH_DefaultDomain_0&hash=item2ee3aa1806

 

(Note the getter and the support, with the dimple in the middle and the angle on it. Also note the number code vertically on the side, and the gold pins. Also note the dual supported stage, beneath the getter, and the shape of the grid. The ones made in Ulm, Germany have a diamond imprinted on the bottom... these are the most sought after).

 

http://www.ebay.ca/itm/TELEFUNKEN-E88CC-ECC88-CCa-6DJ8-6922-ULM-GERMANY-1968-GOLD-PIN-SINGLE-TUBE-/400959682714?pt=LH_DefaultDomain_0&hash=item5d5b0f389a

 

(Another auction with good pictures, note how everything checks out as per above)

 

http://www.ebay.ca/itm/1x-TELEFUNKEN-tube-E88CC-E88-CC-NOS-NIB-6L6-300B-AD1-Eb-AD1-350-380-CCA-/261963352743?pt=LH_DefaultDomain_0&hash=item3cfe3b8aa7

 

(And another)

 

 

Here are the new production tubes, made by JJ in Chekoslovakia. The black label ones are apparently hand selected.

I would also recommend a Russian tube; the Voskhod rocket style actually does quite well with faster genres, such as metal. Instead of buying off eBay, you may want to contact @rb2013 as he has a selection of tested tubes. He is also a great resource for 6DJ8 tubes, as he put up a fairly comprehensive review. He rates the Russian tubes as #1... I do not. He has a lot of believers in the tubes, and I personally found they worked best for fast genres, myself. The Russian tubes are a crapshoot on eBay, and I would strongly urge to consult rb. They are also fairly cheap, although he probably sells the most highly rated ones for more. I haven't heard any of his "holy grail" rated tubes, so I can't comment on them.

 

PS. The model numbers and price of headphones doesn't dictate quality... (eg. the Beyer DT-880's imo are much better sounding headphones than some of their newer models.) Just food for thought. Price does not always equal listening pleasure. 

 

Hi Mikoss,

 

Appreciate the links and the information. I will get in touch with RB2013, was reading through his reviews, makes it much harder to decide now.

Though i will probably get a telefunken (either ones from the ebay or the new ones )...

Some quick impressions of the Aune T1 with Orange Globe tubes and the HD700 combo:

 

Vocals are definitely pronounced - but they aren't extremely in your face. Guitars come through cleanly and distinctly in rock music (I listened to some Eagles and Aerosmith to test this out), though I wouldn't say they are at the forefront of the music. The HD700 definitely is not clinical here - this combo gives it a bit of warmth that works well with most genres of music. Actually, I really like this combo because the Orange Globe tubes seem to tame the treble of the HD700 a bit (which is good for the HD700, but to me is a bit annoying with other headphones). The only complaint that I have is that the Orange Globe tubes don't seem to provide as much bass in comparison to other tubes (like the stock one) - but I'm not sure how important that is in rock music.

 

In case if you're interested, here's a couple of listings on eBay that I found for the Orange Globes:

 

http://www.ebay.ca/itm/AMPEREX-ECC-88-6DJ8-MADE-IN-HOLLAND-ORANGE-GLOBE-VACUUM-ELECTRON-TUBE-GOOD-L-27-/400957560876?pt=LH_DefaultDomain_0&hash=item5d5aeed82c (for one tube)

 

http://www.ebay.ca/itm/SET-OF-4-AMPEREX-ORANGE-GLOBE-LOGO-ECC88-6DJ8-VINTAGE-TUBES-MADE-IN-HOLLAND-/261976576234?pt=LH_DefaultDomain_0&hash=item3cff0550ea (for a set of four tubes)

 

In my experience, you should be fine buying used tubes, especially if the seller has good ratings and/or provides information how the used tubes have tested on some kind of machine. I actually bought a set of four used Orange Globes like the second listing, and the tubes are still going strong more than a year I bought them.

 

*EDIT: Actually, I don't want to sound like I'm shamelessly promoting myself, but if you want, I can sell you some of my other Orange Globe tubes for cheap. Just PM me. But if you really are in Europe, I probably can't sell it to you because shipping costs would probably be higher than what I'd sell you the tubes for since I'm in the US.

 

@chowmien83 Thanks for the links  and you've got a pm.. since i do have an option for you to ship the tubes to the states, just in case you are willing to sell it .

 

 

I cant wait to get my hands on the HD700's and start listening on them...

See if that is an option... before you agree to anything, you can post here with the info he gives and we will let you know if it's legit. 

 

It's up to you though :)

 

Finally got a reply back from seller about other options.

 

-----------------------------------------------

One 6DJ8 I have on hand was Holland-made, probably same factory as Amperex, but it also has a Mullard code near the base. What's more, it's branded by RCA in orange print. I believe it was used in a laboratory scope.

-----------------------------------------------

 

Any good you reckon? Otherwise I'll just go for a refund

Sounds like it is probably a comparable tube... Ask if he can take a pic... Date/batch/factory code and internal construction need to be seen.

I just swapped in a 6DJ8 orange globe to my Aune yesterday, since it's been over a year since I heard them. They're beautiful tubes. Mullards should have a B factory code if they were made in the UK. If the Mullard has a half triangle (delta) code, it's made by Philips/Amperex in Holland.

The B code Mullard 6DJ8's seem to be a bit tougher to find, and can sound quite like the Holland tubes. To my ears, the mids are stunning... Very liquid sounding. The treble and bass is perhaps a bit drier than Holland tubes, but guitar on Mullards is bliss.

All in my opinion. smily_headphones1.gif

So I'm going to say this isn't a Philips Holland tube... I believe it is a Matsush1ta, tube... and therefore I'd ask him for a refund. (You may also opt to just take the tube... it may very well be a Holland tube, or it may sound just fine, even if it's not a Holland tube).

 

Couple of reasons/distinct things that I can see, despite the tube being labelled as a "Holland" tube:

 

- All Philips tubes have four creases along the top. I don't see that.

- The getter flash (grey/silver stuff near the top) does not look like it was made in Holland... way too much getter flashing there. Holland tubes have a smaller amount, normally. Matsush-ta tubes have that slanted style getter, with a lot more showing.

- The nipple at the top is long and thin, looks less like a Philips job and more like a Matsu job.

- Can't see any factory code on the tube, and the pics are kind of tough to zoom in on to see it.

 

Here are what Matsush1ta tubes look like... to give you an idea:

I hope that link works... HF ridiculously censors "sh1t", so Matsush ita doesn't really show very well.

Refund, there are always plenty of real hollands on ebay some as little as $10 at times.$20 easy.

post #7312 of 7313

You guys have some serious knowledge stored away in your heads. Thanks, will ask for refund :)

post #7313 of 7313

Hey you guys!!! (browning points for getting the movie reference).

 

Had my T1 MK2 for over a year now and I'm still running the stock tube. What I'd like is less touch less treble and more bass. Cans are AKG 550. My usage is 80% films 20% music.

 

Budget 30-40 quid inc shipping to France. I was thinking maybe the Voskhod Rocket?
