INSTALLATION
Vacuum tube power amplifiers dissipate considerable heat. It is essential, therefore,
that proper attention be paid to ventilation. The unit should be mounted horizontally
on a flat hard surface. At least four inches of clearance should be provided above the
unit, and at least three inches on the sides. The cabinet or shelf should be open at both
front and back. For more restricted installations, cooling fans are essential.
Optional panels are available to facilitate rack mount installation. Again, it is
important that adequate clearance be provided above the amplifier so that ventilation
is not impeded.
To minimize hum pickup, keep the unit well away from the preamplifier and
turntable and route power cords away from input cables.
THE MV45A/MV75A IS TO BE OPERATED ONLY ON AC LINE VOLTAGE OF
108 TO 125 VOLTS (Also available wired for 100 volt or 230 volt, 50/60 Hz).
