CARE AND FEEDING OF YOUR BATTERIES As mentioned before, most batteries are built for the relatively light chore of starting the engine. Unless you have the room and ambition to install an upgraded high-powered alternator, your system current requirements may exceed the charging capability of your car’s electrical system. When this happens, you have to rely on the vehicle battery(s) to make up the difference. Another factor to consider is voltage. Although the electrical system is considered

Why Tubes? You may know that a transistor is a modern, efficient, less expensive version of a vacuum tube, which is the device that made sound recording and reproduction possible in the first place. Now, the electronics industry has been trying for many years to equal the sound quality available from tubes. They have been able to make transistor amps louder, cooler, more abusable, and less expen- sive than tubes, but to this day, they’ve been unable to make any solid state amp sound as go

VTCSD (continued) VTCSD “follows” the high voltage tube signal STRAIGHT INTO THE SPEAKERS, adding only current in a form of “amplifier power steering” — free from voltage gain or negative amplifier feedback! Vaccum tubes are renowned for their high dynamic range and smooth emphasis of even-order harmonics. The transformer-less VTCSD circuit brings out hidden qualities of the vacuum tubes, including excellent frequency response, smooth “clipping” and high signal-to-noise ratio. VTCSD divides

NEVER, NEVER, NEVER! NEVER USE A U.S.AMP WITH A GROUND LOOP ISOLATOR ON THE RCA’S OR AN ISOLATED INPUT SIGNAL. U.S.Amps are input-isolated at the factory and require an input ground for proper operation. NEVER INSTALL OR MOUNT YOUR AMPLIFIER DIRECTLY TO A SPEAKER ENCLOSURE OR ANYWHERE ELSE WHERE SEVERE VIBRATION IS PRESENT. Protect your investment. Use Common sense. Make sure the spot you choose is well-ventilated and free from dirt and moisture. NEVER USE YOUR U.S.AMP BELOW THE RATED MINIMUM
