Quicksilver Audio Mono 100 Amplifier
Operating Instructions
Thank you for purchasing the Quicksilver Audio Mono 100s. These amplifiers are 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 very stable. KT88 or KT90 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.
PLACEMENT
The Mono 100 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.
SPEAKER CONNECTION
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 labeled C.
There is a diagram on the bottom of the amp that identifies the three posts.
SYSTEM GROUNDING
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. Using an adaptor on the
AC plug of each amplifier, to lift the ground, will solve this problem.
3 AMP SLO-BLO FUSE
Do not use larger than a 4 amp fuse. If a fuse blows, replace and check output tube bias. If there
is a large change, then a 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.
