Resumen del manual
These handcrafted amplifiers feature full differential “front ends” based upon a true instrumentation amplifier topology. Tube Drivers utilize only the highest quality Svetlana tubes in our unique configurations. All of the internal amplifier stages have been designed to have ultra- wide bandwidth together with a high degree of linearity. The tubes used in these amplifiers provide both voltage gain and current gain where they are connected in Cascode and Cathode Follower configurations. D.C. servos are used to control any D.C. offset. These servos are critically positioned in the circuit so that not only is D.C. offset eliminated but also any subtle differences between tubes are internally compensated. These tube stages are then connected to a high current BiPolar output stage that uses the same audiophile quality Sanken output devices featured in the PrecisionPower 2500F1.The output stages receive their power from a highly regulated D.C. power supply which enhances their performance significantly. Very little negative feedback is used. Low feedback designs have greatly improved sound quality having an extremely warm and open sound with enhanced musicality consistent with only the highest quality home tube amplifiers. Service Do not attempt to service TUBE DRIVER products yourself. Performing exploratory surgery on your audio equipment yourself will void the warranty. Many parts of your TUBE DRIVER gear are custom built to our specifications. Our factory parts are not made available to anyone else nor are they for sale. Our goal is to make sure that your TUBE DRIVER product will always sound as good as the day it was purchased.Contact your authorized TUBE DRIVER dealer about obtaining any warranty service through TUBE DRIVER. (See Warranty inside back cover) FOR Y OUR RECORDS Model Serial Number Purchase Date Caution! The extended use of a high powered audio system may result in hearing loss or damage. While TUBE DRIVER systems are capable of "Concert Level" volumes with incredible accuracy, they are also designed for you to enjoy at more reasonable levels all of the sonic subtleties created by musicians. Please observe all local sound ordinances.

This fuse or circuit breaker protects your vehicle from fire in case the power wire shorts to the vehicle body. If you are only using one amplifier, use the recommended fuse rating. If you are using more than one amplifier, add up the fuse ratings for all amplifiers, and use this sum for your main fuse or circuit breaker. Use a power distribution block or fuse near your amplifiers with the appropriate fuse for each individual power wire. The information below is a basic formula you can use to determine current draw. A 50% amplifier efficiency rating is used as an average. This formula is only a guideline. Using wire of a larger gauge can only improve the current transfer of your system. Do not use smaller gauge wire. Total 4-Ohm rated RMS output x 2 = Total Input Wattage Total Input Wattage/Supply Voltage = Current Draw (in Amps) Example:Your MA4100has 4 channels at 100 watts per channel RMS into 4-Ohms (4 x 100 = 400). You would use the formula below: 400W x 2 = 800W/12.5V = 64 Amps Total Current Draw 2 BACK TO CONTENTS Power Wire Calculator Recommended MINIMUM Gauge Total Current Draw Length of Wire to Run (in Feet) 20 - 35 0 - 20 35 - 50 50 -65 65 -85 85 - 105 105 - 125 125 - 150 (in Amps) 1214108 66 42 < 3 10 12 8 8 6 6 42 4...
