Bmichels and for others owning this tube.

I managed to find a small image of where this tube was made! Part of the appeal to collecting these things is the ability to step back in time! Just think. For the first time since your tube was made in this factory 55 years ago this week your going to put it to use. I love that!

In the States using "Franken" just means cobbling many odd parts together to make something.  Like Dr Frankenstein did, thou he with ill results...

Thanks for your explanation, at least my association was not that wrong!

1959 !!!  Wahh... I was not even born ! A time travel indeed !

 

And Yes Ian, Those  Mullards are indeed intended to be paired with Siemens 1T4 that I am still waiting.    Is it the correct match ? 

 

Also, I have received already another match, From Robert this time : 2 Sylvania 3S4 +  2 Tungsram 1T4T.  

 

 

 

 

--> Which combo do you think will sound best ?  Mullards 3S4 +Siemens 14T   or...   Sylvania 3S4 + Tungsram 1T4T

post #1055 of 3473
One thing and this is important, there is no right or wrong match. What I may like you may not!

However, those two pairings are rather lovely and also, the Tungsrams for me are the closest yet to the mythical Lorenz! You could mix and match those two pairings but I really really encourage you to listen with YOUR ears and trust those above anyone else's as that is the best way to find your personal heaven.

In fact I would love that so that I may find pairings I have not thought of yet to try!

Once again though, both those sets are for me top of the tree in terms of quiet and SQ!

some abbreviatons:

 

abr - tube

 

val - valvo

val rl - valvo red label 

lrz - lorenz

sim - siemens

phl - philips

tlf - telefunken

ult - ultron

ge - general electric

eh - electro harmonix

ts - tung-sol

kr - ken rad

 

combo:

 

abr1-abr2

df91-dl92

 

example:

 

lrz - phl

lorenz df91- philips dl92

 

had a brut force tour switching between some combos:

 

val rl - ts kr

val rl - phl

lrz - phl

lrz - ts kr

val - ts kr

val rl - ts kr

 

and finally

 

val rl - lrz

 

- everybody here able to read this without translation guide  confused_face(1).gif

- hope so, typing is much easier smile.gif

- if not force me to save your reading time instead of my typing time deadhorse.gif

 

wanted to verify my before posted ratings, and in general the results are the same. a new experience for me is that the differences between the top combos are so small that now it gets more and more important to give a set some burn-in time (with music not only standby) before rating. especially the dl92 stage needs at least one or two hours to get the sound settled, especially the bass quality and depth will dramatically improve.

 

the final combo i tried and i am right now listening to is the val rl together with a lrz, i.e.

 

valvo red label df91 - lorenz dl 92 combo

 

i tried this combo because the lorenz was warmer sounding than any other dl92 in the first round of listening so together with the val rl i tried  to get a combo that would have

 

BOTH the properties of the VP val rl - phl AND the VT val rl - ts kr combos i posted my opinion about yesterday.

 

i must say it works - this combo has excellent imaging, precision and resolution AND great soundstage, bass extension, depth and texture AND is very precise, beautiful and relaxing sounding, so hopefully combining the best of two worlds.

 

it is easy to write this (but of course true) as the chance to find both a valvo red label df91 and a lorenz dl92 set seems to be like winning the jack pot or being captured by aliens, so not that risky for me to call it my new dream set after some additional listening, no other review on the horizon. sorry, just kidding, i continously try to find additional sets and sources for this tubes.

 

hope we all find our dream set !

tried four different wood stains for the wood of my tu-05 carrying pocket (the picture is not that impressive but gives you a feeling about the different possible colors i have wood stain for):

OK, what is the Lrz ie? I know the Lrz part but I looked and cannot find the ie!

Otherwise I think this is brilliant, now I just have to train my near 50 year old brain into remembering it!

I think your very correct in saying that between the top ones it is much smaller differences and burn in and letting play for a time is very important. I now make it a rule to switch on, wait two minutes for tube warm up then 15 minutes of play time before proper listening, that way I start with the best sound!

I am playing around with isolation again, love the effect of the oak cones but was passing a stone masons today and thought, hmm, lets see if they have an off cut of marble to put over the cork base, then the wooden cones on top of that and the amp resting on the lot of it.

Of course I got there just at the right moment, they had a dumpster and were filling it with off cuts and broken pieces, I spied something that would do and asked them how much and got it for free! The ends are rough but I do not care! So I glued the oak feet in place and will have a proper listen later. I have another piece of marble exactly the same and I am thinking the shakti stone trick might do something. You know, those crazy priced pieces of flat black stone that folks put on top of equipment. I heard an amp once with them on, then off and I actually heard a clear benefit to having them!

Here is a quick shot, will report back later.
BTW, GG, your a genius with all of this mate!

The second from left looks like a close match to the colourfly! I can't wait to see this, it is going to look amazing. I was thinking, for the cut-outs for ventilation you could get some copper or brass mesh as screens!

i.e.  here means something like 'in other words'  from ancient latin language 'id est' - it is - (had this and ancient greek language both 8 years to learn in school).

yes, the second from the left is mahagony wood stain!

 

yes, i removed the tube protection plates from the amp to see the tubes glowing and will make the cut-outs larger to also see the 4th tube. i more and more also think of a brass mesh, the problem with brass is oxidation, a colleague of mine today mentioned why not gold plating everything (mesh, screws, ...)!

 

but the great thing is that you once again got be back on track, the choice is obvious after you mentioned it!

Oh wow wow wow!

This method of isolation and damping is the best yet! The tube tinging is all but gone with the marble on top of the amp and on the base with the amp resting on oak cones.

The background has taken on another layer of black and silent and notes have become fuller and deeper yet retaining air and transparency, in fact transients are razor sharp and quick. The guitar in Krushevo has even more delicacy and yet at the same time a stronger sense of weight as the notes resonate within the body.

Soundstage and placement within that soundstage has become more defined, not subtle to my ears is this improvement and actually it reminds me of what I heard with those shakti stones, very similar effect!

Nice thing with this marble is that it is from a Kitchen counter work top so the underneath of it has a fibre glass mesh glued to it so the stone does not damage the amp!

This is something I really recommend, it damps tinging tubes but unlike silicone rings on the tube it does not rob them of energy or air!

the more i thought about my cradle, the more i came to the result and i am nearly sure to do it this way, 

 

- to order a complete electronic parts kit and a schematic for the tu-05

 

so not stopping half way instead from scratch builing a complete desktop version of the tu-05.

Please GG, tell me your kidding!
post #1065 of 3473

i am not kidding.

 

edit:

 

thinking of a completely separated, balanced double mono double strong power supply with two stronger batteries for both left and right channel implementation, i could think there is room left for some improvements in stability, soundstage and channel separation, also an input selector would be nice!

 

if i close my eyes, i can see the amp standing in front of me at my desk.
