Congratulations from BK Butler

Please accept my sincere thanks and congratulations for making your musical choice my hand-made “MONAD” A100 amplifier. This new USA-Patentedtechnology is an inherently classic design.

Definition:

MONAD: “The ineffable source of all being and existence. Singly superior to all others yet fully known only to itself”…

…

After more than 25 years of tube audio experience in the Professional Music Industry with some of the world's greatest musical talents, I’ve created an entirely new type of tube audio amplifier. Utilizing the incomparable qualities of our proprietary audiophile-grade 300B power triode in SE Class A mode, an amplifier without equal has been achieved. Producing more than 100Watts RMS of power with ZERO negative feedback and greater than 2 Farads (2,000,000 uF) of primary Class A voltage supply filtering on board, the MONAD rightly becomes the new vacuum tube audio standard of the industry.

The Past is the Futureu

The MONAD A100 incorporates the finest application of the pure "Edison Effect," or the essence of Thermionic vacuum tube emissions to produce every nuance and characteristic of the best classic SE 300B triode tube amplifiers at more than 10 times the previous usable power. With painstaking efforts and great attention to detail, the sonic response, load and transfer characteristics of the classic 300B power triode tube have been carefully balanced to operate under optimum conditions at extremely useful and satisfying power output levels.

This groundbreaking design completely eliminates one of the most inefficient and non-musical components in typical 300B SE amplifiers: the Output Transformer. Without hundreds of feet of phase-shifting, musicality-robbing wire and many pounds of induction-generating core iron to overcome, my newly patented current-multiplying DC coupling circuitry allows the 300B output driver tube to directly operate into a fixed ratio-reduced speaker output load. This novel design results in the production of authentic triode tube characteristics many times greater in power than the normal capability of 300B tubes yet all their superior musical qualities are retained.

I invite you to enjoy the finest 300B SE amplifier on the planet. The CNC casing has been precision machined from the finest billet aluminum. Over 100 hrs. were spent on the machining, fit and finish of the case alone. The MONAD A100 is truly the result of a painstaking labor of love for the art. It has been my pleasure to design and build this finest of amplifiers for you.

Sincerely,

BK Butler, Designer and Builder
