Chatham took over Tungsol late in time. So Chatham tubes are the same as Tungsol. You can tell by the internal construction what tube you will buy.

It's better to buy at a safe scource for tubes than a cheap scource. Some sellers are shady.

An OTL amp really has some magic paired with ZMF headphones. The 300ohms driver of is unchained by the higher output impedance. There is no going back after you did experience tubes.

Listening to just the same sounding SS amp each day is my nightmare haha. Last time my Euphoria was gone for repair I was very happy when it did return.

What happened to it?

What happened to it?

I did use 6080 tubes. The tube pins didn't reach fully into the sockets of the Euphoria. That led to a lightning arc damaging a microcontroller inside the amp. Feliks repaired it under warranty and advised me to use savers for big socket tubes like 6080.

You start to really appreciate your tube amp after listening to your Solid state backup for two weeks.

Hi guys,

For tube arcing sacrificing, any cheap headphone is OK? I am seeing some second hand "hifi" tv headphones less than 10€ with 6,3 jack

Also I have a doubt about the turning on process. The test needs to be done every time I turn on or only to test the tubes for first time? When was explained to me in this topic, I understood that was for first time, but now I am doubting if I understood well. Just want to take care of my amp properly

 

[Deleeh]

Don't worry.
Just switch the amplifier on without the headphones in it and when you switch it off, turn the potentiometer back and unplug the headphones - that's enough.
I've been doing it this way all the time and everything is fine.

The only thing I have improved is a small length with a 6.3 mm plug and its opposite pole that stays in permanently to protect the headphone socket.

The Euforia's hardly ever cause any problems, if something is wrong then it's something small that Feliks quickly fixes.

Do you have ZMF Atrium @Renexx? What is your favourite roll for them?

New Linlai 6sn7 arrive today, waiting on Melz 6H8S and Chatham 5998.
Anything else I should prepare.

 

[Deleeh]

Let me know how the Linlai work on the 5998.
I also have the Linlai's.
Remember that they need 100 hours to burn in.
Then the Linlai's will improve a corner.

The Linlai's also work very well with the 6080 Mullards, but the 5998's are very classy.
They could outperform the Mullards, but if you want to be more relaxed, the Mullards are also very good.

You can't go wrong with the Zmf headphones on the Euforia either.it's the right symbiosis.
I've already had 2 Zmf on it and it's something else again.
I really enjoy the Auteur and look forward to getting more one day.

Are those true Linlai tubes?
They look suspect to me.
Here are real the Linlai tubes from Linlai Global and the branding is different.

Hello,
Yes, you are.
We had this discussion months ago.
And they have changed the design of the print.
I was also sceptical because mine looked different.

Mine were one of the first in the series:

“Linlai Global“ branding is different from “Linlai Tube” branding and I’ll standby that.
Linlai even states on their website on their About page about the only accepted logo, which you have.

Others are perceived knockoffs of the Linlai Global brand.

Where did you buy them @Kamsang?

Mine have the same base but say LinLai Global, I bought mine direct from their website.

I bought from china direct from Linlai's webstore in china. I am letting mine burn in at the moment with 5998.

first impression. Sound stage become more spacious. guitar and other instrument become faster and noticable bit more depth and slam. but vocal wasnt my cup of tea. the original set is more 『taste』 like. this set is a bit more plain or i would call linear sound.

 

[Renexx]

I got a pair of Raytheon 6Y6G today and the first impression is very good. sounds like having a Raytheon vt-231 as power tube. Good synergy with russian Reflector 6h8s as my first try.
The Reflector and Foton 6h8s are great first tubes to buy instead of new production tubes. They are readily available and cheap.

Do you have ZMF Atrium @Renexx? What is your favourite roll for them?

When I recieved my Atrium I was trying new types of tubes in the Euphoria.

EL39 is really impressive for low-end presentation. Also has a very holographic dark sound, very analogue penthode sound same like EL3N or EL11/12. These tubes are crazy good for the Verite open.
Best synergy with GEC B65 or GEC 6v6 ( both sound the same as driver) as they are forward for voices and very clear on top end.

GEC KT66 I have two versions. First early smoked glass being a little more warm that's why I combined it with neutral and crisp Visseaux 6v6g.

Second clear glass being more neutral and very crisp. Amazing with warm sounding Canadian Marconi 6v6g. Blew me away how good they synergize.
KT 66 doesn't have that penthode sound. It's forward mids with tight low-end. Amazing for rock music.

Mullard EL32 is a total sleeper. This is an early military smoked glass version. I can't tell if clear glass versions sound different. When I found another pair I grabbed it for quite cheap. Amazing smooth slightly warm sound. Good with 5998.

My usual favourite tube rolls are good for Atriums also:
Sylvania vt-231 + GEC 6as7g
Sylvania 6sn7w + WE421a
Mullard ECC32 + 5998
Melz 6h8s + Tungsol 6as7g

Generally warmer tube Rolls are best with stock pads and more neutral are amazing with Auteur pads.

My Euphoria AE gets fed by a Rockna Wavelight DAC with linear filter.
