Quicksilver KT Series Operating Instructions

Quicksilver Audio KT Mono Amplifier
Operating Instructions
Thank you for purchasing the Quicksilver Audio KT Mono Amplifiers.
These amplifiers have been engineered to have a very wide band width, 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. Any KT series output tubes may be used
without the need for circuit changes or compensation adjustments.
This is an all-tube design and used no circuit boards or transistors.
PLACEMENT
The KT Mono Amplifiers should have at least 6 inches of ventilation space on either side and at
least 6 inches oabove them. If this is not possible, then use a fan for colling.
SPEAKER CONNECTION
Five-way binding posts are used for speaker connection. For a 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.
There is a diagram on the bottom of the amp that identifies the three posts labeled 4 ohm, C, 8
ohm:
4 C 8
Input
100K
Use the 4 ohm tap for speakers from 4 to 8 ohms impedance or the 8 ohm tap for speakers from 8
to 16 ohms.
4 AMP SLO-BLO FUSE
Standard fuse value must not be exceeded. If a fuse blows, replace and check out tube bias. If
there is a large change, then an output 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.
TUBES
The input tubes in this amplifier were chosen for their specific performance characteristics.
These tubes should last between one and two thousand hours. We can only guarantee the
performance of this unit when used with input tubes supplied by Quicksilver Audio.
