post #3136 of 3704
Ok, I had to listen! I really hate telling you this fellow TU-05 owners but this 3S4 tube is without a shadow of a doubt, even after just listening to three of my benchmark tracks ( Visions, Sabbina Sciubia and Antonia Forcione from the Naim label album "Meet Me In London 24/192.. Anne Bisson, September in Montreal from the Album, Blue Mind..Miles Davis Sketches of Spain, KOB stereo 24/192) the best 3S4 tube I have heard to date!

Why? simply that it adds bass I did not think this amp had in it. The bass extension is not subtle. The sound fills out, bass deepens to levels I have heard in other amps but not at the cost of being bloated. The bass we have come to know and love about this amp, textured and detailed still remains but it just goes oh so much deeper, considerably deeper than my last benchmark, the Mullards.

In combination with the Berlin made diamond base Telefunken DF96's which also add bass quality this is just about the most perfect combination to these ears I have heard with this amp. All the pace rhythm and timing is there, the snap and immediacy, the delicate touch in the mids, the sweet crystaline treble but now we have the bass come in to play.

Now, the downside to these tubes is they are made of the same unobtanium as the Marconi's but honestly, if you ever see a pair, grab em! Simply, with all the 3S4 tubes there is nothing to compare.

The added bonus is these are inky black silent tubes. Not a murmur, not a rustle, no ting tings just inky black. Oh, and another thing, more defined soundstage back to front as well as separation of instruments within that soundstage.

I can see why Shikada San has raved about these tubes for so long. Now, all we need is the industrious Japanese members of this forum to go hunting for us. Somewhere in Japan in a dusty wear house must be a box of these waiting for new homes!

Wow that is just heavenly sound to me. So happy at last you have those super rare tubes Ian.

I am still waiting for my phillips df91 tubes to come. Hoping it can eliminate those df96 rustling background sound on my tur06.

post #3138 of 3704
I really hope they work. I have been lucky with all of the tubes I have got, probably 90% have been great but being NOS it is a bit of a Gamble. I highly recommend those DF96 Telefunkens I got from DBtubes, very high quality.
post #3139 of 3704

Thank you Ian. I do have a df96 telefunken tubes. But i don't know whether they are the diamond one or not. They sound very good but still there is a rustling noise at the background. So for now I am still using the silvania tubes. Tubes from Shikada are the best quality tube I have so far.

post #3140 of 3704
Just out of interest check the bases of those Telefunkens. I have had four pairs previous to these and none had diamonds and all were poor sounding and noisy.
post #3141 of 3704

You are right Ian, after I check there is no diamond logo on the base.

post #3142 of 3704
See, thats the problem right there. I don't know who made them but it was not Telefunken. I must admit when I saw the ones from DB tubes they were a bit expensive but I have purchased from David before so knew his tubes were top notch and he knows his stuff about the history of tubes and where they are made and how to decipher codes so I took the chance.

To say they are a night and day difference from the non diamond base ones is an understatement. I was so impressed with the quality of sound of them I have not changed them since getting them. They actually beat my last best pair which were Lorenz's.
post #3143 of 3704
so we can assume that you now also will start with your own modifications based on the schematic of the tu-05?!

it's great that the tubes add some bass. btw that is the reason i always come back to the philco 1s4 tubes because of the much deeper bass.

so i am happy for you that there is a great and outstanding 3s4 with the same ability, but ... as always rare.. rare .. rare. like your lorenz and marconi.

i think a tube rolling party gets more and more nessesary.

So, ianmedium if I understand well your new "gold combo" is :  Kobe Kogyo Corp. "Ten" 3S4 + Berlin made diamond base Telefunken DF96

 

QUESTION: Where did you purchased those Berlin made diamond base Telefunken DF96 ?  I have some Telefunken DF96, but, they are NOT diamond based, and I must say that they did not impressed me a lot !

 

 

 

AHHH again I need to go hunting !

 

Anyway... 

 

In the mean time, I also received something from Shikada San  (but is is much less rare) : 

 

So..some soldering soon to "upgrade" my OUT-41-357 ... :-)

Ah no dear GG! I am about as technically minded as a blind handless lunatic asylum resident! I will happily live vicariously through your endeavours! By the way, any updates?

I am very much looking forward to hearing what you hear as differences with those new transformers BM, As to the present combination I have of tubes now and after listening more and more and to many different tracks I actually feel safe in saying I have no reached the end of tube rolling. I simply could not want for more from this wonderful amp that this combination bring to my ears. So much so I have now screwed on the other tube cover for full RF protection and that way it will stay!

I cannot emphasize enough how important it is to get the right Telefunkens. All the ones without diamond bases and not made in Berlin have been bad tubes both in terms of quiet and sonics.

Sadly I am sorry to say both the stockist that had these now have none, DBtubes is where I got mine from and I have just checked and he has no more. You might want to email him to see if he can get hold of any more though. Also there was a seller on ebay selling the Berlin made ones but they have none left now.

Four Telefunken DF96 with Diamond available here from my favorite tube seller (rosmarie3878):

 

http://www.ebay.de/itm/DF96-1AJ4-TELEFUNKEN-NOS-NEW-OWN-BOX-DIAMOND-/221363335405?pt=DE_TV_Video_Audio_Elektronenr%C3%B6hren_Valves&hash=item338a4870ed

 

you can send him an ebay mail to ask if they were made in berlin.

 

interestingly the tubes are not shown when searching ebay.com (worldwide), so i can only recommend to search also ebay.de when looking for german tubes.

i think some TEN 3s4 are available here:

 

http://articulo.mercadolibre.com.ar/MLA-496272145-valvula-3s4-ten-japon-_JM

 

i think it is from argentina, i do not understand the language but i want to ask that if one of you ordering some 3s4 from this side could send me a PM with the price for two so that i could decide and eventually ask to order also two TEN 3s4 tubes for me ?!

Looks like I should get mine soon, long body with new transformer :)

 

 

Just waiting to finish the leather case....

post #3149 of 3704

Wow, great find GG. I'd have snapped these up and redistributed them to thread members but the sale is now closed. Unlike eBay there's no obvious way to contact the seller, as insofar as I can ascertain only 1 valve sold, so presumably 9 are still available. Perhaps a thread member with better linguistic skills can check out the link and email the seller.
