Ahh, Dart Zeel, that would be my solid state amp company of choice if i had the money!
My Tele's will be shipped tomorrow so coming from Quebec I doubt they will be here until next week not this sadly.

bmichels - it's a heatpipe to cool down something!

 

EDIT: woodcans is right - the correct name is heat sink

Anyone here who has planned to visit or to meet for the first a2p tube rolling party during the next Highend in Munich, Germany?

 

P.S: it's great that holidays are over and the thread is getting more and more active!

Possibly.

Yes, could be as well.

That looks like a very large heat sink, the kind that go on CPU's of desktop computers. Looks like something that gets hot is attached to the rear of the device, directly onto the copper plate. That Dartzeel is a beauty!

just listening to "Ludwig Van Beethoven - Klaviersonate op. 111, c-Moll, 1. Satz Maestoso - Allegro con brio ed appass" with my modded amp and the RFT DF97 - TESLA 1L33 combo (both non standard tubes). the sound is absoluteley amazing. as additional feature of my own build tu-05 you can adjust both anode voltage and bias, the tubes are running with an anode voltage 3 volts higher and a bias of -6 volt instead of -4.5 volt.

 

i am tired, have to work starting tomorrow, holiday is over, but can't stop to listen.

 

with my original tu-05 the above mentioned combo is very spacious and highly analytical sounding, but somewhat bright, as my modded amp has a lower lowest frequency of about 20Hz and improved bass response due to the much larger output transformers, the result is not only very spacious and detailed, but analytical from top to bottom end  (and not analytical in the sence of bright) sounding. have to try this setup with my t5p when i got the additional 4pin XLR jacks.

 

Shikada-san's tu-05 design is really outstanding.

Direct from Herve at darTZeel - 

 

"The new LHC-208 will be available for around June 2014. The retail price is not fixed yet, but the target is around €10k (Geneva FOB price - as all indicative darTZeel prices are given - meaning shipping, taxes, etc., are not included)".

 
Very tempting... :rolleyes:

the only left-right GND connection at the moment is the input jack, because the two (small) input transformers i tested were not as good as hoped. next week i will order and connect two highend input transformers, and then the whole amp from input to output has no left-right GND connection, so completely separated.


Thanks for clarifying for me GG!

Different sound but equally as engrossing, Both very very musical though.

let's take a break and forget the technology for a while and let's listen to some music :

 

 

 

24 bits High-Res version downloadable here :-)

 

Enjoy my friends...

Slightly bigger than our TU-05 : Line Magnetic 41.2 212 Single Ended mono amplifier

 

 

or more reasonable... Line Magnetic LM-219 IA (2 x 24w) :

Yay, My DF96 Telefunkens from DB tubes here in Canada have arrived and I am pleased to say they are proper Tele's with the diamond bases (DB may be a bit more expensive but he is reliable with his descriptions. I shall clean the pins and pop them in and burn them in for a while. I am really excited to hear what "proper" Tele's sound like as all the others I have purchased have not had the diamond bases, not been made in Germany and have been so noisy as to be unlistenable!
post #3074 of 3473
OK, now I see what all the fuss is about with Telefunkens! These are night and day different to the ones i have had before. Even though they are not burned in I can hear they are a superior tube. Top end goes on forever as does bottom end which is a surprise as I always associate German tubes with air, transparency and beautiful top end but with not a lot of bass. These have it all and then some!
I have combined them with my Mullards and would say this combination has it all. Very musical, good deep bass (for this amp) and lots of air around the notes and soundstage. Beautiful soundstage presentation as well with these Tele's.
Dead quiet, no ting ting's or rustling, just clear black sonic background. Early days yet but I think this will take over as my golden pairing!

do you have picture of those "magic"  Telefunken as well as their boxes as well as the detail of the diamond base ?  Interested to see if they are diffferent from those I got..
