Thread: Tube Rolling for Lampizator Level 7

I have ordered the Sylvania 5u4g and 5x4g with National Union 45.

Currently stock is 101d Psvane white base and 5c4u.

What should I be trying for best imaging and soundstage.

I think Mike Lavigne at WBF has a pair for sale. They dont work well in a standard GG, as the voltage output is too high, but they are heaven in a B7...I know, i tried it myself...

The Lampizator is a tricked Lite 7 with tubed rectifier stage. It was built new last month.

Haltron/Zaetrix/Fivre double mica (ceramic spacer) 5r4gy, Brimar 5z4, RCA/Jan world war 2 (pre 1946) double upward sloping getters 5r4gy. They cost about $100 on EBay. Date code for 1944 is "H".

More expensive is the Philips metal base GZ34 and the Brimar 5r4gy FE code.

If cost no object, then the Elrog 300b or the vintage WE 300b with the Takatsuki 274b recti.

Also the Kron Px4/45/300b are mid high priced but have good reps.

The Lampi EML 45 mesh globe is terrific but sold out for now.

The Psvane "UK design" 300B is very good and costs about $350 a pair on EBay.

Do the current EML 45s and 5u4g exceed what you have listed apart from the tatsuki and Elrog ?

One or 2 people swear that in general Kron beats EML, and that Elrog/Takat beat all except possibly for the horrendously expensive WE vintage tubes. Takat recti is like $850 and a pair of Elrogs is about $1,200.

Here is a list of tubes and relative prices:

The KR PX4 seems very popular, would be nice if someone that had tried them and compared to EML 45's could chime in.

As for the rectifier don't have a clue, some say the 5u4g from EML cannot be beaten, some say go full nos with either U52 GEC or Marconi 5u4g.

Gopher,

Fred could you comment on your experience with KR and EML tubes.

Iam comparing the National Union 45's with my Psvane hifi 101d and I hate the very forward presentation of the Nation Unions compared to the 101d's being placed in the middle not so much in the front.
Also the vocals are very thick with the National Union 45.

I don't know, might not make a difference.

The NU 45's sound a little veiled too

KR 274b is a much better recti, the 101d is very good for output valves, and much better are KR 242s if you can find them. KR 300bs are also better than the 101dd, and I haven't heard the Elrogs or Takatsukis but they should be too, though mich more expensive.

Have you tried the KR PX4 ? And EML rectifiers

Sold my EML recti after listening to KR, and haven't tried px4 yet but the 242 takes the big 7 to almost GG levels

What EML rectifier did you have ?

5u4g

Both audiophile bill and I on hearing the KR had no doubt regarding purchasing it

I have no doubt that you liked the KR 274b, but in this price range it's more to do with sound signature than which one is better hence the question on what the difference.

I listen mostly to orchestral and opera so better will have to be for soundstage, dynamics, musicality, control and details of complex music.

So in general does the 274b sound better compared to the 5u4g ?

I have heard the WE274b replica by PSvane is great too.

No the replica is nowhere close. The original might be. I haven't heard that and Tak

Do you know what the KR 274b cost as I cannot find them online

Can't remember exactly but I would have paid around 360 - 400 EUR for 1 recti

I was using the EML 5u4g for 6 months or so and put in the Tak 274b a couple weeks ago. I am so enamourd with the Tak I really can't speak more highly of it. I am using the EMLabs 300b driver tubes on a Lamp SE GG.

Good to hear, what does the Tak cost ?

About $1k ea.

That certainly is not in budget.

Will have to get the EML Mesh 5U4G

I would be happy to sell you mine. Are you interested?

Please message me the details.

Anyone got any EML45 or KR P4X for sale ?

I paid retail $250.00. http://www.tubeaudiostore.com/eml5u4gmesh.html.

Sent you a message

Hallo Norman,
i will go with the Lite7 (xlr-> premapli, spdif, AES for cd player as transport...)
I do you have more Lampi dac tested and I'm sure you can give me a good feedback... (im in Switzerland too)
A "friend" from italy say me that Totaldac is the best Dac today available but Lampi with Tube for me is better.....

I^m im contact with Pawel....I go place my order in the next day for a Lite7......(i dont will the volume controlle, I prefer use a separate preampli...)

newer listen but im' sire that the Lampi give me a great sound!!! ( I go usa a Lumin S1 as music player..)


greets

Hi Db33, i am close to Gva. A pal in Genf has the Lite 7 as does Stewa in Bsl area. Another pal in Argau has a level 5 special version. I have a GG and will soon have a Der Seibener for demo which will be passed around in CH for people to try out for a limited time. If interested you could get on the demo list or arrange with me or Stewa if he is willing to hear our Dacs. Stewa has great tubes.

Hi, Lampi give a very Great sound in a system. I use solid state (the Best) in ampli & pre-> i had try tube preampli but ihmo not at the level from SS products) ampli with tube (and NOT the Audio Research -> only a name without Performance especially in the LF......)

Der Seibener -> this Dac is only for DE/CH/FR...not for other country. if you go recieve a Der7. in test please give me your point of view.

I go pull the trigger for a Lite7. Preampli is already in my system and I use it. Pawel say me that is not the best have a Lampi with volume control and use a extern pre.....simply setting = better sound....

a friend in Itlaly say more and more over Totaldac....is the best, live sound....but with SS a Dac with tube is sure a greets...open your mind!!!

Sorry but if you send back the Der Seibener (or others Lampi) you lose the VAT paid at import. right?

Hi stewa bist du in der nahe von Basel richtig? ich bin in Tessin....auf jeden fall kannst du mir Beschied geben auf Lite7? hast du xlr anschlussen?
privat mail?

For anyone who has a head DAC I have a new set of tubes coming . I'll post when I get them. This should be better than the vt99 tube , I need a few weeks to get the tubes and adaptors

Hi, I am selling my KR 274b. This rectifier valve is for sale at 182 EUR. KR would additionally charge you tax (usually 20%), bank charge, and postage. Postage is free from me in EU and UK but I will charge elsewhere.


Hardly used since I don't have speakers to play. In the Lampi we preferred it much more to the EML recti

What were the characteristics differences between the two.

The EML is too laid back and lacks the soundstage, bass, and dynamics of the KR rectis. In KR rectis the special Lampi 5u4g is better, but only a few restricted numbers were produced and are sold out, so is unobtanium.

Btw, my KR 274b is now sold.

I have about all
listed in recti and output anyone wishing to ask me feel free to
al

Hi,
Have a Lampi B7, currently using KR 5u4g as recti. and KR 300b output. Would like to get feedback on what changes KR 242 output would have? [amps are 90W tube mono's]

thanks,
Jay

Thank you Joe. Seems to be a very good audio forum...I'm glad to be here.
