Lampizator Valve / Tube Rolling Review Thread

[dctom]

I have recently obtained the KR 5U4G RK.
I have been using the EML mesh 5U4G previously in my GG. Initially not a big difference in sound, however after a week am noticing greater transparency, definition and improved spatial qualities.

A valve of many colours depending on how you connect the grids.
Convert a balanced lampi into a differential output 46 lampi?

So no UX4 socket?

So no UX4 socket?

No, 5 pin is used like my EML45V4 tubes.

 

[Zero000]

I have them and RCA 245 as well.

I know I remembe

That is a bad news.

Have a little hope for a different experience.

Ked is full of audiophile pop poo. Don't listen to him. Some say his ears are full of wax.

I like the Sylvania VT-52, Cunningham as above and Tung-Sol 6A3.

People will rant on about what the best tube is but that is missing the point of a Lampi. I think it's about enjoying a wide variety of different presentations over time.

Sure in hi-fi terms EML's best will show the older NOS tubes a lesson. But tone and sometimes less detail is just more enjoyable. Depends on mood I think.

EML and KR sound all the time? Boring, bored, bored, boring. Zzzzzzzzzz.

I can dig that Justin. Get a nice stash and roll baby, roll.

You just nailed it with this one!

If someone would like to sell his 101D Replica, please send pm. Preferably from EU due to customs. In fact I need quad.

Did I say already that my favourites are - since a few weeks - KR PX 25 ?
Yes, you were both right Goran and Christoph
Plus a recifier Fivre 5R4GY recommended by Trab - thanks Grzegorz ( Greg in English), I like it more than RK 5u4g.

Glad to hear that Marslo!
Aaaaaa - can't remember where I missed the part about that recti...you like it more than RK 5u4g? Must be a bingo one than as that RK was a killer one...

Just more subtle than RK , RK is more « muscle valve ».

Seems like there is something in the saying 'Italians do it better"

Yes, OLD Italians

 

[Trab]

Thanks Marslo, it's nice to hear you like it.

Only certain Italians do it better

5R4GY Fivre, grey anode, double D getter and dark brown base.

This tube is unlike any other in quality of tone. Just different from the very first moment.
Worth give it a chance.

Double mica recti.

 

[wisnon]

Wow , picture shows its the single mica...

 

[RichardA]

Trab which 5r4gy tube do you use on your NAfF amplifier ?

 

[Trab]

Hi Richard !

The grey Fivres described in the post 234.


Needless to say, choice depends on:
- the rest of the tubes in NAF: 5687 and ecc83,
- tubes used in pre and Lampizator,
- system, and personal preferences.


I'm also able to use in NAF:
Brimar 2 x D getter black anode, brown base,
Fivre 2 x D getter, grey anode, black base. Both give stronger bass control and more weight.

As you see I like 2 x D getters.

When gray anode is in NAF I usually avoid that tube in Lampizator, and vice versa.
I seldom roll tubes in NAF as at the moment I found the combination I like.
I do roll rectis in Lampizator, with pleasure .

I quite like the FIVRE.

Was running Accuphase's first ever monoblocks from 1975 last night and the combo I settled on was the FIVRE and KR PX4.

I find the FIVRE has the most expansive imaging of any recitfier I have.

Did you say Fivre?
Having had PX4 for a year or so strongly recommend PX25 from Kron.
