Exactly one year later. Same song on a similar system. But now boosted with Tarandus upgraded pre and power amps, a MASSIVE subwoofer and a prototype of my first ever MC stage. Ready to rock RMAF 2017! (To best hear the music, go to Instagram)
In FIVE DAYS I'll be at the 2017 Rocky Mountain Audio Fest in Denver, Colorado. Come visit me and Thomas O'Keefe in room 1008! We'll be demonstrating some fantastic products,for instance the new 1.1 version of Boazu.
New batch ready and they're perfect! This number 80 is the first of six Tundra Mono power amplifiers heading for an enthusiast in the United Kingdom.
Another Review! Alan Sircom has tested Sagatun Mono and Tundra Mono and praises them in the July edition of HiFi+. Yippie!
Demo in Stockholm. Brought some goodies: JBL 3677, Ofil stands, bunch of amps. Wife helping
First magazine review of Boazu! Chris Frankland gives it a thorough listen and a Best Buy rating in HiFi Critic No 1/2017. Yippie!!
A temporary pause in my currently very digital laboratory, assembling and testing Boazu 025, heading for Gothenburg, and two phono stages: One Gaio and one Slipsik 6, both serial number 100!
Tarandus! That's my latest upgrade for all pre and power amplifiers. I've done ten of them this week. This old friend is Tundra Mono number 020. It was built the 19th of February 2013, sold to the United Kingdom, upgraded in March 2015 and now with the Tarandus upgrade fitted ready to be hooked up to the lab HiFi for a final check by ear.
Late night work, inspecting and testing Boazu number 002. I received the first six units today. Production is really slow, at first due to ironing out various bugs in the assembly and now because only ONE person builds them. This guy has held the highest level of quality and the decision was taken that he will continue building all of them. Thank you for your patience! I think everyone who's ordered a unit will get it before Christmas.
Good morning! Tomorrow is HiFi Live in Windsor, UK. I'm bringing my first integrated amplifier, Boazu. The one with ZERO features and music so sweet you'll be wondering what hit you.
Rocky Mountain Audio Fest, here we go! Thomas and I have been tuning all day and it sounds, well, superb. (To best hear the music, go to Instagram)
Laser marking a BOAZU front plate. In one month, it will be rocking the room 'Sandringham 9' at HiFi Show Live in Windsor, UK. Please come by, I promise not to play any audiophile jazz!
A BOAZU case being stamped and cut by laser. In October this new baby will be presented at RMAF in Denver, Colorado. Come see us and hear it in room 1008!
Final tweaks: Never underestimate their impact! I have 18 combinations to evaluate by ear. Which one makes the music most captivating, most touching, easiest to understand and appreciate?
I'm back! And arriving just now, ten minutes ago, is the second prototype board of my product to be launched in October. This is the board I spent five weeks optimising before vacation. Among other things, I have learned how to distribute the inter-layer capacitance and use it to boost performance. Now it needs soldering and assembly. I am so anxious to hook it up and play some music with it that it feels like my blood is carbonated.
Vacation, at last. Wife reading. I'm making plans in the shade. Not shady plans, bright ones. Excited about the fall to come. Will be at RMAF in Denver, Colorado and The HiFi Show Live in Windsor, UK. Hope to see you there!
Vacation? Not yet. I've spent four weeks drawing this new baby and it needs at least one more. Hope it will be out in October. What it is? I can only say that I think you'll be impressed.
Sweden, midnight. Two days before the longest day of the year. Rising from a hot bath with friends Jacob and Stefan. A deer walks by, looking curious.
Comparing various phono stages with Paolo Nobile at Key Systems in Rome. Winner: Slipsik 6
-L4562 requesting to dock!…-Please state purpose…-Testing circuit alternatives, sir…-And where is your motherboard?…-Being drawn, sir…-Saving time, I presume. Very well, IC, standby! Temperature set to 362 degrees. Steady now. And 3, 2, 1, Solder!
This is how a large part of April was spent: Building and shipping my latest baby, Slipsik 6. Each unit takes three and a half hours to assemble, tune and test. Some have said it's the best Moving Magnet phono stage ever made. I'm too humble to comment on that, but apparently proud enough to mention it!
With my son Martin at Juhl-Sørensen in Copenhagen, testing a Steinway model D. Tears in my eyes.
Demonstrating stereo versus Mono amplifiers in Den Haag
Meeting Marco of Hexagon Audio in Amsterdam. Tomorrow is the opening night of his distribution of Lejonklou in Germany and the Netherlands. Cheers!
Recognise the song? Demonstrating Sagatun and Tundra with Sonny at HiFi Huset in Dragør, Denmark. (First time I'm posting a video clip, so curious to see whether it can be heard on my website lejonklou.com as well)
Delivering amplifiers in sunny Copenhagen
Assembling the very first Slipsik 6! The black narrow spaced circuit board has sensitive tracks buried below layers of shielding copper. And the incoming high voltage is screened by the assembly shown above. Excited to compare it against the prototype – which one of our Test Pilots won in a drawing last weekend. Congratulations to 'More want more' from Denmark!
So very, very pleased with the new batch of Tundra 2 amplifiers. Before they arrived, I couldn't sleep because I worried something would go wrong. There are too many things that can go wrong when manufacturing precision electronics. But after having done the final tuning, measured and listened to five units: Wow… I simply can't find anything that isn't perfect.
Back in stock! After months of hard work, the new batch of my main musical machine Tundra 2 just arrived. Thank you for your patience!

New phono stage under development: Slipsik 6. If you want to become a test pilot with a chance of winning the prototype, apply before the 30th of September at www.lejonklou.com/forum/viewtopic.php?f=1&t=2960
The 1st of October at 7 pm, Anders at Tonläget HiFi will be demoing his new passive filters 'Referens' for my favourite loudspeaker Klångedang T1, using Sagatun Mono and Tundra Mono amplification. Just heard about it and now I'm trying to arrange things so I can be there.
Back at work! Upgrading Tundra power amps to version 2 and Sagatun pre amps to version 1.1. Almost no power amps left in stock! New batches need my attention, so I know what to do this weekend…
First week of vacation. Not thinking of the exciting projects that are now on pause. Not thinking of what will ship in August. Not thinking of the test board that might be ready to listen to in September. Not waking up in the middle of the night by what seems like a smart idea. Just focusing on the here and now, on the ball approaching the hole.
SUMMER DEMO 1st July 18:30 at Ljudkompaniet Uppsala Sweden. Linn sources and speakers, Lejonklou electronics – including brand new Tundra 2 and Tundra Mono 2 amplifiers. Welcome!
A final cup of Tea at Hidden Systems before the demo at 19.00. Preamps Sagatun and Sagatun Mono to the left, Tundra 1.2, Tundra 2 and Tundra Mono 2 in between the speakers, which are passive Linn Akudoriks. Sounding very good!
Mother is visiting. So many things to celebrate today! One of them is that on Tuesday (19th of May) my latest power amplifier Tundra 2 will be introduced at Hidden Systems in Hartley Wintney, UK. Call Chris to reserve a seat and I'll bring the drinks!
What now? So far three of my amplifiers have been upgraded to new and higher performing versions during 2015. Everyone seems more than delighted with the improvements. But didn't I promise to upgrade another model as well? I just can't seem to remember which one. Please help!
Pre-production work: My daughter Tuva Lejonklou helps me measure and sort power resistors. Why? Because the highest precision you can buy is not accurate enough for a batch of Tundra Mono 2.
THIS is how my mornings start; with a bowl of strong brewed Yunnan Premium. And TONIGHT I will be demonstrating Tundra Mono 2 at Tonläget in Gothenburg, Sweden. Along with the announcement of a small but significant surprise. Hope to see you there!
Two things that make me happy:Our 10th anniversary website, made by the marvellous guys at Spire in Uppsala, is up!Our 10th Sturtevant Richmont torque tool has just arrived, complete with its calibration certificate. Essential for fine tuning our products before they are shipped to the customer.
Meet our new best amplifier: Tundra Mono 2, with 1.2 kg of copper inside, cooling the circuits. Also a trim feature for optimal performance – regardless of how it’s positioned (for instance on an open table or hidden in a cupboard). The feature compensates for long term drift as well. The originals can of course be upgraded. Here I’m working on number 006. Good to see you again, buddy!
And they are shipping!Both my analogue stereo pre amplifier Sagatun and its no compromise cousin Sagatun Mono.
In exactly ONE WEEK from now, my analogue pre amplifier Lejonklou Sagatun will be presented at Hidden Systems in Hartley Wintney, west of London. Hope to meet you there! If you can’t make it, the second demo will be at Tonläget in Gothenburg on the 21st.
Laser marking on the front plates completed.
The final proto is doing a quick round tour, visiting some enthusiasts whose judgement I trust and value. Last minute feedback, two weeks before the final assembly starts. Nervous? You bet.
Only weeks until launch. An unexpected delay occured in the manufacturing of the enclosure. Apparently I had not approved a drawing and everything stopped. Well, that turned out perfectly. Because in the meantime, I had made some improvements to the communication link and really wanted to squeeze in a miniature sliding switch on the rear panel. When I was notified of the stop, I could add the switch before production resumed.
106 days later, the circuit is final. 34 areas have been methodically investigated and optimised. More than 500 listening tests have been made (yes, I know it sounds crazy). Final prototype performs like nothing I have ever heard. Parts are being purchased and production is approaching. Feeling very good!
Two thirds completed preamp board. Ten more switches and then a long series of tests.
Ready to solder the brand new preamp board. Excited!
Finally!! After six weeks of drawing, thinking, calculating, dreaming, erasing and redrawing my new analogue preamp board, I’m DONE. Apologies to everyone that I have neglected. This picture shows the first layer of four.
