Very interesting design, I like the volume light. I thk the bag could be more fashion.

Congratulations German Guy, looks very similar to mine though yours has a matt grey plate from what I can see. Is yours made in Holland, I can't quite make it out!

I am looking forward to seeing the Lorenz tubes you got from him. just remember the pin cleaning as it makes a difference as it removes slight traces of noise I have found.

Also, though after about ten hours you will have the tube settled in it will take about another 50 I have found for it to fully come on song.

I really recommend following Shikada San's advice on using this amp. I turn mine on and let the tubes settle for a minute, then play music. I find after about twenty minutes of playing one has reached the perfect listening state, everything is nicely warmed up (though the tubes never get hot, at the most slightly warm to touch)

When finished listening always turn the volume knob to zero then unplug your headphones. I am guessing the amps made now will have the separate on/off switch and I really encourage anyone purchasing this amp to make sure with Shikada san that this is the case with their amp as the one flaw has been with the combined on/off, headphone jack. When I can bare to part with mine I will send it back to him for the free upgrade!

Here is a shot of my beautiful amp with the Phillips/Lorenz combo and the rest of the gear I use with it. Together the sound is just beautiful and I am so happy for all of you who are about to experience this amp!

Ianmedium - thanks for this procedure - it is similar to the way i use my tube amps - so i can be sure nothing to do wrong with my tu-05!

I have grown up with grandmas and a lot of aunts at a time when tube tv's and tube radios in germany were rather common and also started with electronics at the age of ten as one of my hobbies, so this thread is a nice way to share and renew long forgotten knowledge and experience!

By the way, while i am so lazy to take pictures just with my tablet and not with one of my dslr's your pictures are just looking great. Are they out of a mobile phone or made with a camera?

P.s. 1 - just checked the tubes - nothing written about where they were made.
P.s. 2 - i am not as old as the second sentence may imply :-)

Thanks for the compliments on my pictures, I just snap, I use a Leica which I love.

I too am old enough to remember tubes ( or valves, I am British) in everything, heck I remember when they used to sell them in my local garage!

Hmm, I wonder where your tubes were made? I have seen Phillips that have been made in their radiotechnique factory in France, likewise in their Mullard factories in Britain. Can you see and let me know what all the printing on the glass says as I might be able to find out where yours have been made!

PHILIPS DL92 - PA1 - L9C AND SECOND TUBE L8L

Found the complete philips code table - can be downloaded here:

http://www.pauls-roehren.de/downloads/PhilipsCodeListAB.pdf

With reference to this table:

PA -DL92

1 - Internal Code - nobody knows

L - Manufacturer - Bruxelles - Mazda

8 - Year 19x8 L - December

9 - Year 19x9 C - March


So i assume they were manufactured in December, 1958 and March, 1959

Can't think of the tubes being manufactured in late 1948 / early 1949.

Mr Künzig has just responded (yes at 11 pm) that he will also check the codes.

PHILIPS DL92 - PA1 - L9C AND SECOND TUBE L8L

Yes, there was a time when one of the local electronic shops offered hundreds of nos tubes for one Deutsche Mark each, had never thought that one day i would be angry not just to have bought all of them!

P.s if you are interested in old leica slr's and lenses you should call (not offered in the online shop) Foto Sauter, München (Munich, Germany), get connected to the desk for used equipment, they have a lot to offer, just for some hundred euros.

It's not often that I stare at a thread photo and smile! Nice image Ian. Please remind us in which order you're using the Lorenz/Phillips combo in the TU-05.

 

Cheers,

Andy.

i am sure in the right order :-) . Just kidding ... these are two pairs of different type so i think there is no choice other than using the df91 in the two df91 sockets and the dl92 in the two dl92 sockets or was there a misunderstanding on my side? Do you mean ...which socket is for which tube?

I've got this ... will it fit in the TU-05 ?  tongue.gif

 

post #326 of 3704
Thanks so much Andy!
In the voltage gain stage (1T4/DF91) is the Lorenz and in the power stage (3S4) is the Phillips.
German Guy and other new users this is really important!

All the sockets are the same 7 pin bases so be very careful you put the tubes in the righ order! The manual that comes with the amp shows the correct order please read the manual to make sure your putting themin correctly as if you don't you will damage the amp!

Bmichaels! I love it! Kronzilla tubes ! A friend of mine who is an audio reviewer has that amp at the moment in for review, each tube cost the same as our amp!

bmichels,

 

Either you have very small hands or that tube is a whopper! wink_face.gif

 

Cheers,

Andy.

Is it me or is there something very Fritz Lang about this amp!



According to my friend who is currently reviewing it the sound is amazing only exceeded by the heat!
post #329 of 3704
And to bring it back on topic I copied this fascinating picture of the innards of a DF91 from the excellent Mullard Magic web site.. Oh, talking of Mullards I saw a DF91 mesh plate the other day, sadly only one available but I am looking for more!



And for lovers of this amp I recommend an incredibly beautiful CD that I purchased last week and arrived this week and have been listening to little else!

The artist is Nima Ben David, the instrument the Viola Da Gamba, the CD, Resonance on the MA Recordings label.


http://www.marecordings.com/main/product_info.php?products_id=165

Though the album is most certainly an audiophile recording of the highest quality ( I did not think one could get a CD to sound this good!), unlike many audiophile recordings the music is incredible, such a meditative album with incredible playing and emotion.

The album was recorded over three days in a little chapel in France and the music makes the hair on the back of your neck stand up with the realism of it. A perfect accompaniment to this amplifier I feel and I highly recommend it!

Todd (the owner, producer, engineer and artist of MA recordings) also threw in a sampler and I have immediately ordered another recording from him as the guitar playing on the sample I listened to was other worldly!

That album is..

http://www.marecordings.com/main/product_info.php?products_id=68

Here is a short piece, on the album but not the actual recording to give you an idea of Nima's playing and below that the piece from Krushevo that I listened to on the sampler, both albums made for this amp I feel and really show off its abilities wonderfully.
Krushevo..
