Congratulations! Which one is yours? Isn't there a mini balanced jack on the green one?

The modder's diary part 23:

 

yesterday finetuned the voltage filter boards and also modified the filament voltage of shikada-san's internal power supply boards to be somewhat higher for the capacitors to be decoupled by resistors so the hole filament voltage filter better working.

 

i modified the anode voltage capacitors directly placed on the amplifier channels and added 7 times the capacity, which is a real benefit as now my hardcore test track (tschaikowsky, telarc, ouverture, 1812) can be played at live level without even the idea of any bass distortion, a real improvement.

 

also i modified my grado style headphone replacing the 6.3mm jack by a 4pin xlr one and did the same on the amps side.

 

after also building a new input board with input transformers and a potentiometer (of course a Shikada-san original one) the amp now fully works double mono.

 

another benefit of the input transformers (good, but sure not exceptional, just neutrik studio ones) is that they transform the signal 1:2 so providing some additional "amplification".

 

i must say that the result was or is worth the effort up to now, stellar sound, increased soundstage wide and depth (the depth interestingly caused by the voltage filter board), more stable presentation, very clean, clear and deep bass at any level and (the highs of the tu-05 were never harsh or something like that) the highs are don't know how to say more relaxing, sweet, not harsh, not grainy, beautiful, precise. also the imaging got more pin-point like than before, which is a real benefit for me as this was one point for me to be improved due to the small weakness of my grado style headphones in this area.

 

the overall presentation has changed in a way hard to describe. in the past i often have written in my tube reviews that the impression of the soundstage and feeling for the space were based or build by the highs or by the lows, bass, and this now has gone. the presentation is absolutely coherent, nothing wired or to think of left, just beautiful music where all fits together.

 

on the other hand when listening to the right music, f.e. techno, Yello, UK dub step, the amp has such a fun to play, to rock, in German Language we say "geht ab wie ein Zäpfchen" (impossible to translate), bass pulses just explode, you can listen at any level without any change in sound stage, any compression or sound degradation. and again, absolutely homogenous.

 

at the moment and at the end of my holiday, i think i can now paint the tango output transformers and then put everything together in my desktop case.

 

P.S. forgot to mention that due to the doubled battery capacity the amp has a runtime of nearly 15 hours.

Congrats mtthefirst! The long waits finally ends..
post #3034 of 3525
Happy New year everyone, back to normal now and home for me, GG, your Mods are looking amazing, well done sir, mtthefirst, congratulations, I am looking forward to your impressions.

Just a note to anyone who has sent me a PM this past month, I can see I have a few but I cannot access them. Not sure if its the system or my computer but I cannot get into them so whomever they are from I apologies for not replying, I can't see them!

Quiet for me, glad the AK240 has come along as I have little or no interest in it unless it pulls a rabbit out of the bag and manages to sound a great deal better than my AK120 so thats a relief, no emptying of pockets here.

I do have some news on the tube front. quite a while ago Shikada san wrote me and said he was going to try to find a pair of "TEN" tubes for me as he knew how much I wanted a pair and he has told me how good they sound. Well, he found a pair! He is going to use them in the 05 at a show in February and once that is over he will ship them off to me. They are in the 3s4 section so it will be interesting to see how they fair next to my favourites, the Phillips!

Currently I am running the Phillips/Mazda combo, a nice warm relaxing sonic signature with just enough sparkle, perfect for winters listening I feel. This combination as well suite the LCD's much better but still, my preference is either the T5P's or PF's

GG, once again, congratulations on such wonderful modifications, I am in awe.

I think this is going to be an interesting year on the ASP thread. I am very much looking forward to hearing what people think of the new transformers, who knows, I may be tempted to send my amp back to have them fitted!

Congrats on the Ten! I'm still living with one and it's in the box waiting for partner (who may well not be compatible so probably a short term relationship). I wonder where he sources these things!! They're so hard to find!

 

Although I've had my TUR-06 since Aug, I hadn't really paid much attention to them until I got my Alpha Dogs and the synergy between them is (my)mindblowing. I've not tried tube rolling the TUR-06 on the ADs though. I can't remember what the Sylvanias are now that I've been on my NECs.

THE TU-05 FOR ME IS AN OUTSTANDING AMP AND VALUE!

 

i have the feeling and it is important for me to mention here that the tu-05 is an outstanding amp and a great value (as it is).

 

when i got the tu-05 and after some tube rolling (but even before) there was NO amp in my inveventory that came even near to the sound quality of this little gem.

 

one of my next actions surely wll be to rebuild my original tu-05 as it is or was to enjoy this sound quality wherever i am.

 

this amp rivals big desktop amps and especially related to its tiny size, portability and battery driven design the sound quality can't be judged high enough.

 

i had a lot of amps before but all gave me maybe one benefit but always at the cost of one weaknees, the Cayin HA-1A much to noisy with low impedance, the Alo Contintental V2 with great soundstage but weak bass, the Vorzüge AMP Duo just the opposite, but then i got my TU-05 (thanks to a recommendation of Ianmedium), WOW, ... ,no compromise, improving really every aspect of sound.

 

a thousand thanks to Shikada-San for his openess, great support in general and that he supports me in such a great way designing my own tu-05 desktop version making all this possible.

just want to mention that i have over 150 tubes "on stock" and as i am really focussed on my beloved RFT97 - PHILCO 1S4 combo feel free to ask if you want a special tube absolutely not available after intensive searching. found it interesting that less and less different tubes are available on ebay, so it gets harder and harder to find ones dream set.

post #3038 of 3525
As always GG, your a credit to this forum.
I just bit the bullet and am trying a pair of Telefunkens again! As some may know I have not had much luck with them so far, my first pair turned out not to be Tele's the. The next pair were faulty though I loved the sound.
I was looking on my Canadian suppliers inventory this morning and I saw he has some 1979 Berlin made, diamond base NOS Tele DF96's tested ( and I trust his testing from experience!) the were a little pricey at $15 a pop but I really want to hear what good Tele's can do so they are on their way!

The little green one is mine and yes, that's a Kobiconn mini balanced connector.

found a nice site with articles around highend but want to post this link

http://tech.juaneda.com/en/articles/managingvibration.html

as the way to build a base and kill resonances is very similar to ianmediums base he made for his tu-05 (yes - granite) improving the sound of his tu-05.

Very interesting indeed: a very affordable way to enhance an existing system !

Hi GG,

thank you for sharing your amazing efforts in the quest of musical excellence!

Truly awe inspiring.

Could you please explain for me what the advantage is in changing the 6.3mm plug on your Grado style headphone is?

 

 

"in German Language we say "geht ab wie ein Zäpfchen" (impossible to translate)"

 

Also out of curiosity I tried a Google translation of the German phrase you quoted and got this :- "goes down like a suppository" o_O

Is this what you meant??

:P

It's arrived.

Congratulation !

 

What source and what Headphone will you be using with it ?

a headphone connected with an 6.3mm jack shares one ground line for both channels, where a 4 pin xlr connector makes it possible to connect the left channel of the headphone to the left output transformer and the right channel to the right output transformer without any connection between left and right, so completely separated.
