PLACEMENT

The M80 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.

Operating Instructions

Thank you for purchasing the Quicksilver Audio M80 Mono Amplifiers.  The amplifiers have been engineered to have
a very wide bandwidth, extremely low distortion and good dynamic range.

The front end circuitry used in this amplifier was developed by Quicksilver and is unique to the audio industry.  It is
D.C. coupled for low frequency stability, and nulls out any change in power supply voltages, negating the need for
regulated power supplies and their inherent sonic problems.

The 12BH7 driver is D.C. coupled to the output tubes.  The output tubes are tightly held to their operation voltages.
Reliability and output tube life are improved because of no inpiut to  screen grid arc-over.

Superior bass performance is offered by this unit.

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

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.)
