THE LAST ORGASMIC SPARK OF THE FIRST CENTURY
OF THE AUDIO ARTS
THE FINAL ASCENSION TO MICRO-POWER
My ego wouldnt let this mellenia end without me defining the high point of this, the first century of the audio arts. This is my job as Guildmeister, and quite frankly with the intense thermionic creativity going down all over the world, I was up against the wall. How could I create one piece of audio gear that would embrace the entire century of tube art? Because I was stumped I emailed Duke Ellington because I can always count on him to take me to a higher place, especially when he is playing for me in my living room.......
And it worked and I immediately flashed back to a conversation I had at David Bernings workbench when I saw some Nuvistors...and my heart jumped a beat....there arent many of us left alive who know what they are. There werent many who were brave and stupid enough to wrestle with these 1/2 inch long metal little tubes ( Nuvistors were introduced to be the first subminiature tube and two years latter in 1956 transistors appeared and end of Nuvistors) which love to sing (microphonic)...and David and I ruminated about our Nuvistor suffering. At one time during the early days of New York Audio Labs I manufactured the worlds only Nuvistor moving coil cartridge head amp and a Nuvistor power supply for the Win Strain Gauge cartridge....cool, but stupid, stupid.
So as soon as the Duke did his job I got on the phone and called David...my only nuvistor soul mate...and described the challenge I was facing and then I asked David if he would pass judgment on my concept for defining the high moment of the first century of the audio arts. I would only proceed if David agreed that this concept was the crowning achievement of the tube arts for this century. He did and got so excited about the concept that he demanded to do the design work.
ASCEND TO MICROPOWER
Put on your seat belts we are about to launch our rocket powered thermionic dialectical express sled...we are blasting off into the time conundrum of the audio arts. If we want to experience the "Big Bang" we have to go back to a time when a one watt amplifier was equivalent to an Atomic Bomb, in terms of power. If we want to expand our hearing bandwidth so hear we can hear the first moment of creation we need an amplifier that can produce the kind of power that sparked the explosion of the audio arts that we are all now surfing........but only amplified in refinement.
Now you will under understand why THE BIG BANG AMPLIFIER, the worlds first and only:
ALL NUVISTOR TRIODE (ONLY ON PER CHANNEL ) SINGLE ENDED AMPLIFIER THAT CAN PRODUCE A GUT WRENCHING 250 MILLIWATTS OF TRIODE GLORY....
(now buckle your potty safety belt)
ALL NUVISTOR SWITCHING POWER SUPPLY
THE CONCRESENCE OF THERMIONIC COOLOSITY
HAS BEEN REDEFINED
Look at the schematic....mind blowing isnt it. Have you ever seen anything simpler, proving that I am the master of LESS IS MORE. Of course this is possible because the Nuvistor has a gain of over 100.....and David and I discovered the one company in the world that can make both the special single-ended output transformers and the torroids for the Nuvistor switching power supply.
But as you know the specs never describe the real world performance of any circuit, which is why I spent two weeks auditioning the pre-production amplifier to be sure of my conclusions. I also invited friends for their own independent evaluation.What is so mind blowing about this amplifier is that the audio circuitry is only two inches by three inches.
IBS TRANSFORMER COMPANY
THE MASTERS OF MINIATURIZATION
The high tech world of electronics is amazing and we wonder how it is possible to get thousands of transistors in a tiny chip....and how it is possible to wind a output transformer that is only one half inch square. Obviously the transformers are the key to the success of this circuit and they are true works of art. To appreciate them you must look at them under a microscope to see how precise the windings are. These are open frame designs.
Clearly, custom made transformers were needed. We were very fortunate that the IBS Transformer Winders Co. Inc. who are the masters of high tech micro transformers, got excited about this project. IBS is a family run business and David and I made an appointment to meet with them to design exactly what we needed and to watch how these little transformer jewels were made.
Mr. Itsy Bitsy Spider, the president and chief engineer greeted us at the door and immediately took us to his winding shop. David and I counted twenty four spiders in white lab coats spinning spider wire on to the ferro-beetle cores (Note: ferro beetle cores are made from beetles who live in Pennsylvania iron mines). We then were introduced to the "master winders" who migrated from Switzerland years ago where they were employed in the watch business. We watched as they took the ultra-fine spider web wire and wrapped around the ferro beetle cores...at an amazing rate of speed and with great precision with all ten hands operating at full speed. What was so amazing to me was how incredibly small all of the transformers were.....but from a spiders point of view.... they are gigantic.
Over the next two weeks David received many different samples from IBS and built some prototypes and sent them to me for auditioning. David and I agreed that one type of output transformer, not only measured much better, but there was no doubt that it was more dynamic, had better harmonics and generally had the best expanded aural matrix....and it was made with pregnant Mexican Tarantula spider web wire....which is extremely expensive...and rare.
THE SECRET OF SOUND QUALITY OF THIS AMPLIFIER
Because I believe hard wiring sounds best, David and I were faced with another challenge...wiring up the circuit for production. I suggested that the best strategy was for David to get very very small so he could supervise the manufacturing at the "grass roots" level and he agreed. I watched with a magnifying glass as David schelped around resisters and how he used his teensy beensy blow torch to solder all the connections. When David got into trouble wiring the Nuvistors, because of their very fine wire pins, Itsy Bitsy Spider and an apprentice spider winder were there in a jiffy to help David complete the work.
HOW DOES THE BIG BANG SOUND?
This is the most unusual amplifier I have every experienced. For example:
As you know one of the great advantage of using switching power supplies with tubes is that they create very quite circuits. This is especially important with Nuvistors which were put on this Earth to turn audio designers into jelly fish.
The last time I experienced the kind of beautiful silence this amplifier is capable of, was when I was crossing the Nefu desert with Lawrence of Arabia... at night with all of the stars of the cosmos twinkling above. With the Big Bang you are directly connected back to that moment of silence right before...the Big Bang happened....you are almost at The Twang Before The Big Bang....the noise floor is minus 250 db!
This project would have been a complete failure if the circuit was not cable of producing the kind of dynamic music energy we associate with the Big Bang...the creator moment....which is also possible to feel when we are the potty the morning after the typical American Thanksgiving feast. You know the glory of experiencing that primal moment of reality.
I feel very fortunate that I may be the only critic in the audio industry to be a qualified judge of dynamics...and it is because of an accident I had in Hawaii. In 1996 I was in Hawaii for the International Thermionic Surfing Contest....champions from all over the world came and demonstrated their skills at surfing the amazing thermionic waves that travel from east to west all across the Pacific. All the greats are there from all over the world. I was especially impressed by the cool surfing skills of Team Eskimo .
During a break in the competition I decided to jog up to the top of Mona Kauai volcano carrying my surf board for some exercise and just as I got to the top I started to feel a rumble...and the rumble got more intense......I was thrown to the ground....Holy Cow... I am in the middle of a volcanic eruption...and it is during moments like this I am so thankful for my training in the U. S. Army........I looked over my shoulder and see a lava flow heading right for me.....I grab my thermionic surf board, jumped on it as the lava flow reached me and I am surfing a volcanic eruption....there I am surfing on a lava flow down the side of Mono Kauai..... which is why I can judge dynamics better than any other...and let me assure you this is the most dynamic amplifier I have ever experienced....and it emerges out of the volcano that is erupting in the audio arts......and the hot lava flow is your imagination....and it sounds great with all of the Madonnas records, when I am chewing gum.
SOME TECHNICAL NOTES
You probably noticed: there is no insertion loss in the IBS transformer which means it has zero resistance, which is pretty amazing because it implies that pregnant Mexican tarantula web wire is super-conductive. When we realized this, David and I realized that, quite by accident, we had made the breakthrough in superconductivity and should start a new high tech electronics e-commerce company and do an IPO and become billionaires.
HOW TO USE THIS AMPLIFIER
This is a potentially lethal weapon, and I must demand that you do not show it to, or play it for, anyone who owns one of those mega-amplifiers...tube or transistor. With shark lawyers ready to sue anyone for anything, you could be sued by one of these wrong-headed owners, because once you show him your Big Bang Amplifier which is only 4.5 x4.5 inch, and weights 4.4 ounces, and he has a heart attack........hello law suit.
The Big Bang is not for everyone but for the man who wants to make a statement, this is major indeed.
A mono pair cost $284,567.30 and offers Ongaku owners the opportunity to ascend to a much higher and more expensive place.
