Quicksilver Audio V4 Mono Amplifier Operating Instructions

Thank you for purchasing the Quicksilver Audio V4 Mono Amplifiers. These amplifiers have been
engineered to have a very wide bandwidth, extremely low distortion and superior dynamic range.
The output transformer used in this amplifier is based on the best designs of the past but uses superior new
materials to achieve a very high level of performance. The high frequency characteristics of this transformer
are so stable that many different output tubes may be used without the need for circuit changes or
compensation adjustments.
This is an all tube design and uses no circuit boards or transistors.
The V4 Mono Amplifiers should have at least 6 inches of ventilation space on either side and at least
6 inches above them. If this is not possible, then use a fan for cooling.
Five-way binding posts are used for speaker connection. For better sonic performance, we
recommend using the screw-down part of the post rather than banana plugs to connect your
speaker wire. Make sure the ends of the speaker leads do not touch each other. The rating on the
back of your speaker system will determine whether you use the 4 or 8 ohm tap for the positive
lead. Connect the negative or ground to the black post marked C.
Your Mono Amplifiers come with three pronged grounded AC plugs. In some systems, where the
preamp is also grounded, a ground loop may appear as a low level hum. Plugging the amplifiers
and the preamp into the same AC outlet will usually take care of this problem.
Standard fuse value must not be exceeded. If a fuse blows, replace and check output tube bias. If
there is a large change in any tube, then that tube is probably damaged. If the bias has not changed
then the cause of the fuse blowing may be due to other problems, such as poor system grounding,
unstable preamp, shorted speaker, etc. Interchanging the amps between channels will help
localize the problem to either the system or the amplifier.
