UNPACKING THE TEMPEST II INTEGRATED AMPLIFIER

Tools required: # 2 Philips Screwdriver

WARNING - This amplifier uses voltages that could cause injury or
death. Never open the amplifier while it is plugged in, and always wait
at least one hour after turning the unit off to unplug and open the unit.
Lethal voltages can remain in the electronics after the unit is
unplugged.

The Tempest II has been painstakingly inspected for cosmetic flaws during and
after assembly. In order not to damage the cosmetic appearance of your amplifier
it is important that you follow the unpacking instructions carefully.

1. Remove the Styrofoam packing material from the box, and remove the two

small white boxes. One of the boxes contains the Output Tubes, while the
other contains the power cord and remote control.

2. Lift the unit from the box, and carefully remove the protective plastic bag.

Remove the shipping pallet from the bottom of the amp. The pallet serves two
purposes. First, and foremost it acts to tie down the mechanically isolated
transformer platform. Secondly, it provides strength to the main chassis. Both
of these are critical to ensure that no damage occurs in transit.

3. Save the packing materials. The packing materials and box have been

carefully designed to protect your valuable equipment during shipping so you
don’t want to throw them away.

4. Remove the top cover of the amp using a #2 phillips screw driver to remove

the 10 cover screws. Using a glove or a clean dry cloth , install the tubes using
the diagram in Figure 1. The Output Tubes will have a label designating their
proper locations.

INSTALLING THE TEMPEST II INTO YOUR SYSTEM

Amplifier Location:

The Tempest II depends on natural convection flow patterns for proper cooling.
To ensure proper cooling, the unit should be located in a position so that the
airflow is not impeded. The unit should not be placed in a fully enclosed shelf,
and should have a minimum of 8 inches of free space above it, and 6 inches of
free space on either side.

Connecting the Tempest II to the Loudspeakers:

The Tempest II provides options for either 4 or 8 ohm speakers. The impedance
selected will depend on the speakers used. Consult either the owner’s manual for

Rotary Bias
