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-Patented technology is an inherently classic design. Definition: MONAD: “The ineffable source of all being and existence.
Description: BK Butler’s MONAD A100 is a 300B Class A vacuum tube-driven monoblock power amplifier. Both RCA and true BALANCED precious metal plated input jacks of the highest quality are provided. The RCA input jack and the 5-way speaker output binding posts are top of the line Cardas. The 300B vacuum tube is proprietary Butler design and manufactured per our specifications. Sprague polypropylene capacitors, Vishay-Dale mil-spec 1% resistors are employed throughout the entire audio chain.
condition in the case of a direct short circuit between the + and - output speaker binding posts. 7. Over Temp Circuit Breaker: Opens the speaker relay if the heatsink temperature exceeds 115 deg. C. If this occurs, the amp will automatically begin operate again after the temperature has decreased sufficiently. NOTE: BE CERTAIN THAT AIR FLOW IS COMPLETELY UNRESTRICTED ABOVE AND BELOW THE AMPLIFIER. THIS AMP IS DESIGNED FOR USE ONLY AT ROOM TEMPERATURE WITH ADEQUATE OPEN VENTILATION AND CIRCULATION.
Inputs: The highest-quality Rhodium plated Cardass RCA-type input jack will accept the line-level signal supplied from most pre-amplifiers. The silver plated Neutrik XLR accepts true balanced signals. The input gain has been internally preset to equal full (100 Watts) output at 8 ohms for an input sensitivity of 1.7 Volts. The input impedance is a very compliant 47K Ohms at each input to accept a wide range of signals without undue loading.
Cable Quality: It has been our experience that you generally get what you pay for in cables. A good set of shielded input connection cables coupled with large gauge, high quality low-loss speaker wire is well worth the investment. Do not degrade the remarkable performance of this amplifier with inferior connecting cables. The Marvelous Vacuum Tube: Triode Vacuum Tubes were the first method of practical audio amplification patented in 1907 by Lee De Forest.
Tube Reliability: It's interesting to note that until the 1960's, tubes were used in virtually every area of electronics including aviation. When people flew on a commercial airliner, they literally trusted their lives on tube-powered avionics. So, aside from a common-sense warning to take care not to break the glass, there is very little reason to be overly concerned about the 300B tube used in your amplifier.
