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 VE

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. It is good practice to keep the shielded

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. At first, he used an open

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. The 300B tube installed in your new Butler amplifier should last as lo
