PLACEMENT

The Silver 88 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.

SPEAKER CONNECTION

Gold plated 5 way binding posts are used for speaker connection because of their sonic

performance. Placing the amp directly behind the speaker with a very short speaker wire will

further improve the performance. The connection to the 4 or 8 ohm tap will be determined by the

rating on the back of your speaker system. The C terminal should be connected to the common,

ground, or negative terminal of your speaker.

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. Plugging the amplifiers

and the preamp into the same AC outlet will usually take care of this problem.

4 AMP SLO-BLO FUSE

Standard fuse value must not be exceeded. If a fuse blows, replace and turn amp back on. Check

the bias on each output tube. If the bias on one tube has changed by a large margin or there is no

bias, then that tube is probably bad and should be replaced. If the output tubes appear to be okay,

then the cause of the fuse blowing may be due to 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.

Operating Instructions

Thank you for purchasing the Quicksilver Audio Silver 88 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 any type of loudspeaker may be used.

This is an all tube design and uses no circuit boards or transistors.
