The EL34 35W stereo amplifier from ANK Audiokits provides some of the finest EL34 amplication available today. It comes in 4 versions as either integrated or power versions. The custom designed and manufactured EL34 IE-Core output transformers or our impressive double C-Cores are at the heart of the system extending the quality of the entire audio spectrum to extraordinary levels. We have packaged the kit options at a very reasonable price to allow users to experience the wonderful aspects of the EL34 tube.

The EL34 IE-Core has been carefully designed to leverage the best possible sound using more traditional transformers. As you can see in the photo right we love big transformers, and this amplifier has serious mains and choke performance.

The pre-amplifier

To provide either an integrated or power amplifier option we designed a 12AU7 pre-amplifier section to then drive the EL34/ECF80 power amplifier stage. The board is installed on the inside front of the chassis. This ultra quiet tube stage adds the desired gain for an ideal integrated amplifier and is ultra quiet. You can experiment with the many 12AU7’s available to get different characteristics to your overall sound.

The pre-amplifer version also comes with an Elna selector and extension kit which ensures minimal signal paths.


     
     

The power amplifier

Both the EL34 integrated or power amplifier versions have updated power supply sections complete with a large low inductance Choke and sport Mundorf’s latest power capacitor technology.

The ultra quiet mains T-190 and our newly designed PCB make up the EL34 power supply section. The 3mm thick PCB houses the EL34 & ECF80 driver sections and every detail has been taken into account to ensure clean build and the large chassis and signal ground traces are expertly designed for ultra quiet operation.

We are now also using CMC black teflon valve bases which have an ultra snug fit into the board.

 
 

 

 
 

The EL34 tube

Mullard introduced the EL34 in 1953 and it has since has been used in many famous amplifiers ever since including manufacturers such as Marantz, Dynaco, Acrosound, Heath, H. H. Scott and Eico for example. All EL34 amplifer versions comes with the Shugang EL34-B which is a nice example of the tube.

 
     
 

 

 
 

I have spent many hours enjoying my favorite Al Di Meola 70’s guitar fusion albums on my own EL34 C-Core amplifier. Incredible punch, mind blowingly realistic guitars, the detail, definition and information at the upper registers are all the characteristics I enjoy with these amplifiers.

  It sounds fantastic. I'm particularly impressed with the bass, clean, smooth flat response, and plenty of output - surprising for 35 watts.

They are going great! What a wonderful amp! (L4 El34i) It has almost as much "air" and "presence in the room" as my KT88 single-ended amp, and almost as much punch as my favorite-solid-state-of-all Creek mosfet 5030se. What a great combination.

Hi Brian, today the L4 EL34i sing!. Very sweet, charming and balanced. Not any hum and noise. I love it! Thank you very much!

The really good thing is that at long last I have got my dream-amp (L4 EL34i) – Thank you Brian!
This is the best thing I have got in my audio system and its impact on the sound and pleasure of listening to music (any kind of music) is just unbelievable!!! My so far bass-shy Yamaha speakers got very vivid, lusty and full of energy now! I had no idea that they are able to produce such nice low freq. tones!

Hello Brian,
I took the opportunity to use the L4 EL34 amp to drive some very expensive Sonus Faber loudspeakers (not mine I wish!). The results were staggering, this amplifier with its upgraded components is in a class of its own. I am looking forward to building pre-amp.

  Thanks Brian ! The L4 sounds very special. Like you said the virtues of SE with the drive of PP. I heard many EL-34 based amps but none like the L4. Congrats !.. The power supply looks robust, great and yes, no hum whatsoever. I also get a good read out from the TP's (21.5V for all the tubes).

  yes, true, as others wrote as well: this amp is deadly quiet! No, and "no" means really "NO", noise, hum, or whatever, even when you turn volume end-right without input signal. Frankly, my QUAD 606, sizzles a bit then! So the L4 definitely provides a real deep-black stage and background for the music, from my perspective one very important prerequisite for a good sound.
- Instruments are drawn clearly, clearly separated with space around - sometimes too much space, but here I am really sure that this WILL change with burn-in, this looks like a typical effect. I checked that with Jethro Tulls "Songs from the Wood", "I am the whistler", if you know what I mean: all these bells, pipes, etc. etc. in that background of heavy guitars, drums etc.
- And really very nice sound colors!!! Emotionally: - Enjoyable. ABSOLUTELY enjoyable. From the first minute. Fascinating!

A friend of mine and I heard this amplifier at CES in the Focus loudspeaker room. I'm a single ended 2A3 guy myself. Well...the Focus people played this Flamenco dance track on their 90 db speakers (Hi Fi Flamenco was the disc). You talk about kick'in @$$!!! When the track was over the room was full of people and everybody exhaled all at the same time! I'm now taking a second serious look at push-pull.

  Dear Brian,
I spent some time listening to the EL34 amp tonight. The amp has 50% less hum than any other amp I own (<1 mv AC). This is a big deal when driving 105 db efficient horns. The EL34 is liquid, authoritative, dead quiet and throws an amazing sound stage. My wife was instantly impressed which isn't always the case but said that the sound was great and kept getting better the more we listened. Dark Side of the Moon has never sounded better!

  The L4 really DOES rock, no question about it. I put on some 'Stones and it was like the Maxell ad......timing, power, punch, volume, pitch........MUSIC. Classical as well......strings are absolutely sweet; some Shostakovitch string quartets for instance, or Vivaldi wind instruments. Voice is great too; all sorts of intonations you've never heard before.

  Words are difficult to find, it's unbelievable, I never heard a sound like this, Harmony so rich, phenomenal energy, extraordinary sound scene with a surprising depth. And the voices ! How to describe the voices, with only tears of emotion... With Audionote the music is simply true. Thank you very much Brian for having allowed me to hear that. Now I have only a single envy : to try all your kits and the next is the DAC!

  Quite an achievement this amp, I find it hard to even drag my old one out of the cupboard now. So Andy (Grove) was right - this is a new type of sound - full of punch.........soul..........and detail! Yet it carries loads of finesse as well!

  "I just want to say that I've spent the evening with the most wonderful EL 34 amp I can ever imagine. I just listened to Ruggiero Ricci on a London Blueback totally mesmerized by the performance. I just couldn't move. I switch to Alison Krauss - So Long Wrong and am equally impressed." --- I find it extremely engaging. Great job!!!

  One of the fantastic things with this amp is that it has a lot of body and weight in the sound. And that is without losing any detail. And the dynamics will totally rock your socks off! To this day I have not heard an amp that can perform as the L4. Playing that good in all levels is something I have not heard from any other amp so far. And I have had many really expensive amps tested in my system!"
"an amp that gives you a huge soundstage, transparent full bodied sound and totally kicks ass.
