Quicksilver M60 - Manual

Quicksilver Audio M60 Mono Amplifier
Operating Instructions
Thank you for purchasing the Quicksilver Audio M60 Mono Amplifiers. The amplifiers have been engineered to have
a wide bandwidth, low distortion and excellent dynamic range.
Quicksilver believes simplicity provides the best sound and reliability. The AC signal in the M60 travels through only
one input tube, one driver tube, one coupling capacitor, the output tube and the output transformer. With only five
devices in the signal path, very little coloration is imparted to the signal.
This is an all tube design and uses no circuit boards or transistors.
PLACEMENT
The M60 Mono Amplifiers should be placed where they will have plenty of air circulation. Allow
at least 6 inches of ventilation space on either side and at least 10 inches above them.
SPEAKER CONNECTION
Screw terminals are used for speaker connection because of their superior sonic performance.
The output transformer wires are silver soldered directly to the screw strips eliminating any output
wiring. 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 1 ohm tap is for special applications only. 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. Using an adaptor on the
AC plug, to lift the ground, will solve this problem.

This device has very high internal voltages. Never operate with the bottom removed!
Never operate your amplifers with the speakers disconnected.
To prolong the life of your amplifiers, never turn them on and off within a short period of time
(45 seconds.)
