I received some time ago already some NOS EL39 I measured and was able to build decent pairs.
As everyone have already said this is a fantastic output tube and it pair wonderfully with all the strapped pentode/tetrode. It also need some burning time to give it best.


I received cheap EL12N RFT/RSD tube i wanted to test for my next amplifier.
I made a test using them as driver and with EL39 as output and i can say that it is a good driver no hum, no noise.. It is not as warm as EL3N (miniwatt) but it have deep controlled bass and is very dynamic just a bit bright. (tubes a just out of the box). IMO, it is a good tube for Live recording Jazz, Rock, Pop...

It does not sound as good with original 6H13C and drain to much heating current.

So to me the EL39 is a magic powder for Euforia it cost much less than GEC 6AS7G, it ais a long life pro tube, do not need external heater... I've made a adapter also compatible with EL34 6L6 KTxx tubes.

@connieflyer I hope that you will be able to fit EL39 in your 20th year anniversary Euforia even keeping gold psvane.

EL39 has been one of my favourite powers for both Elise and Euforia for a while now and performs very well with EL11 as drivers. At the moment I'm running GEC KT88's driven by GE 7581's in Euforia and Tung sol 6550's driven again by GE 7581's in Euforia both of which are fine sounding combinations.

Are these vintage or new production Tung-Sol 6550? Do they use the same adapters as KT88? In any case, how would you compare them to the KT88 sound-wise?

OK, used up my 3 questions. Thanks!

Hi LoryWiv.
My Tung sol 6550's are vintage, not nos but still good condition. Yes they take the same adapters as KT88 's. I've not listened to the GL KT88 for some time now so would need to perhaps pop them back in and remind myself of their abilities.
The GEC KT88's have replaced my 5998's and EL39's as my favourite power tubes but can be expensive. I've found that the GEC's can be well used but still sound great in our amps which no where near push them to their capacity and allows more scope when checking for good deals on ebay.

Still experimenting with EL39 (year 62), using the small sister EL32 (Year 43) same RT Brand.
Nice look and sweet sound with HD800S [imany Live At The Casino De Paris] and T1 ( ) [Björk Biophilia] .
Not a jazzy day...

I have heard the Euforia has good synergy with the Meze Empyrean. Can anyone confirm this?

 

[connieflyer]

H 1 has had that combination and he thoroughly enjoyed it some of the best he has ever heard. He still watches This Thread so he may chime in. I am using the Sennheiser 800 and the Oppo pm-1 as my main phones and they both are excellent with the euphoria. I have both the standard fee for you and the 20th anniversary euphoria and those phones work very well indeed

You have the standard fee for you? I feel Android autocorrect is at work

 

[connieflyer]

Actually if you own both amplifiers with those very same headphones there is a fee involved!

Time to start rolling, EL 39 with stock Psvanes

Hello

I have a euforia about to arrive and I was just wondering how do you switch from using it as a headphone amp to using it as a pre amp?

On the front is the headphone jack - this is for using the headphones.
On the back are the RCA preamp out jacks. Just connect the cables to your amp /receiver and now you can use the Euforia as a preamp.
And if you want to, you can use both together (there are people who like to use speakers together with headphones). However, using both together could affect the volume.

Question about tube equivalencies and compatibility with Elise / Euforia: As best as I can determine 6L6 / 6V6 are similar to KT 66 / 88, EL34 is similar to KT77, and EL37 is similar to 7581. I have used adapters from Deyan to run KT 66, 77 and 88 as well as 7581A in Elise. Based on this compatibility is it also expected that any 6L6, 6V6, EL34 or EL37 would work equivalently well using this adapters I already have? Any landmines I should be watchful for? Thanks...still trying to educate myself about the depths, dangers and rewards of this tube rolling rabbit hole.

I know for a fact Meze has the Euforia in their factory. But I have not yet the cash for the Meze.

Sad day, tried my EL39's with stock Psvanes and no joy. Since last use one or both decided to wear themselves out. Through pre out, distortion in bass, and after letting them settle in for over an hour, improvement yes, but not without some distortion. They were used when I got them so no telling what they had been through. Next tried the "special El38" and those were much better. But after a while with headphones could discern slight anomolies. So this morning tried the Dario El38's with phones, and these are doing great. No distortion, wide open, wonderful sound. With use these for a while and find a different driver. Eventually going back to the GU50's and KT88's but want to hear more combo's before that.

If anyone is considering selling their Feliks Euforia and live in the UK/EU give me a message.
