post #391 of 3488
Congratulations chaps on your orders for both the 05' and 06'!

I was just looking at the boards in the 06'. They look beautiful, looks like hand made, no mass made circuit boards there! I bet they are made of bakelite like the 05' so you will get that vintage whiff if you open the case up as you do in the 05'!

Power supply is on the right, such neat workmanship which one has come to expect of ASP amps!



German Guy.

I won't jump as i have two and want others to experience Lorenz but I must admit I would jump on even a single one especially looking at the boxes they tell me they are pre ITT days so of much higher sonic quality!

Nah, when #1 & #2 were taken I got cheeky and asked "How about #0?" but that's his :p. So #1 & #2 went to customers. Oh well, at least I'm getting one :P.

Tube collecting and rolling is addictive. As it's inexpensive, easy to do and very rewarding. There's something magical about using a component that was originally manufactured decades ago. Pin cleaning is very cathartic too, it's a quiet moment of introspection before inserting the tubes and firing up the amplifier. 

Cheers,
Andy. 

ph34r.gif Thats me Andy! I swear there is not a day goes by that I am not scanning permutations on google or eBay on the hunt! I can't wait to get the RCA's, just think, something made 70 years ago being used for the first time, it is like being transported back in a time machine which is half the fun of this tube/valve collecting!

Oh, and Shikada san said he does hang out here and looks at what is said with an eye always on improving his amps. He said he does not want to join in as he does not want to stop the honest discourse but I said he would be warmly welcomed here and that it would be great to have him join in.

Anak, seeing as your a MOD now (congrats BTW) would he have to become a member of the trade member to join in?

One last thing.

I see the Tung-Sol RCA's have all gone, congratulations to all that managed to snap them up! I just wrote to Robert (the seller) who is in Vienna.
I explained about our amp and the tubes used and asked him if he could tell me if he has any more of the types we need and if not can he keep a look out. Also I told him about the Lorenz tubes and asked him if he could keep an eye out for those as well. I sent him a link to the amp as well so he can see what we are using the tubes for.

Being in Austria I thought it worth a try as German Guy is so kindly covering the bases in Germany (thank you again GG, for all of the work your putting into that!).

Just had a very detailed telephone conversation with the shop owner of the link above:

So as a summary (ianmedium you are the lucky guy) lorenz stopped own production of tubes in a very early stage of selling them, instead rebranded and sold tubes where most of them were made in the united states. He mentioned for example the companies silvania, tungsol, general electric.

Before he buys any lorenz tubes, he checks pictures and codes of them to be sure of the origin.

So it's like playing russian roulette what you get.

But besides the set on ebay he has no lorenz df91, maybe one can understand now. One of the first sentences when calling me back was 'why the hell do you want especially lorenz?'

Maybe we should start looking for Usa made tubes?

The only company producing tubes in their own factory until near the end was telefunken, while a lot of siemens tubes are rebranded soviet tubes or from jugoslavia, Hungary or tschecheslovakia.

Just updated my previous post!

I predict your going to love this amp with the PF's, just a match made in heaven I feel!

As to the compatibility, Shikada San offers the option of two gain settings out of the three offered 8~32/16~64/32~200 So looking at what you need I would say go for the low and high gain options.

In my experience with the FAD Heaven S/ PF's I have heard no hiss with better quality tubes. The stock ones though sound good are I find a little noisy. Once music is playing it is not heard though in my experience.

The most silent tubes I have used to date are Siemens, Lorenz, Phillips and Radiotechnique which are absolutely silent.. However they are all NOS so it can be a bit of a crap shoot. The cheapest tubes I have purchased so far are the quietest so price is not that much of an indicator.

Mullards are pretty quiet as well and I have found with a good number of hours on them most quiet down.

The upgraded volume pot is a must I feel, simply the best pot I have used and even at the lowest volume no channel imbalance is to be found.

If your going to use your amp near a computer or cell phone I recommend the metal tube guards as they cut out all the electronic interference.

Other than that make sure your getting the separate on/off switch and headphone socket. I have a feeling he is doing that as standard as the combined one was a weak spot but double check with him to make sure.

I am really excited for you, the PF's are just magnificent with this amp, the soundstage is incredible as is depth and the way the amp pin points all the instruments in the sound stage, something the PF's excel at I feel and this amp shows that even more!

 

reading all your posts i think i have to take some valium to survive the next 3 weeks until i and my pf viii have the same amp to listen! :-)

Fascinating.

I purchased my pair from an excellent seller in Italy. Mine are a (I was going to say rare but now it seems, Unobtanium) Stuttgart made pair and that is apparently a big difference as most Lorenz's like so many other brands are just re-brands of other makers tubes.

Just like my so-called, made in Holland tubes but made in the UK!

This apparently is very common practice but I don't think even Telefunken were immune as the pair i purchased don't have the diamond impression in the glass on the bass which is a way to tell if it is a Telefunken made product

I have asked the Italian seller if he can get any more but he said that in the thirty years he has been selling tubes he has only seen one pair of these made in Stuttgart and I have them!!

The Siemens tubes myself and Andy have have been confirmed to be German Siemens made.

Yes if he joins, he'll have to inform admins he's a MoT.

 

All this talk about tube rolling makes me wanna buy some even before my TUR-06 has been built. But I think I should read up this thread more first.

It also might be a bit of "apples and oranges" in terms of sound from both models...

That's very true since the TUR-06 is a hybrid.

we should make an arrangement with shikada san (name correct?) that he only sells his amp to people that have provided us with at least 4 sets of original lorenz tubes :-)

I was thinking about tubes with the 06's so it is funny it is brought up now.

Going by Anak's review I am leaning towards German tubes for a more airy sound with slightly larger sound stage as the bass goes deeper I have a feeling the German tubes would give that bass a nice tight feel to it.

This is just my gut feeling. I just think the traits of the German tubes (silky, detailed top end, accurate but not so deep bass and simply perfect mid's) would be a great match.
