Rogue Audio Tempest Vacuum Tube Integrated Amplifier - Manual (Page 6)

6) Select Mode - The Rogue Tempest features a user selectable
option of either Triode or Ultra-Linear operating modes. Some
listeners prefer pure triode operation, however, it does limit the
power output of the amplifier to approximately 40 watts per
channel. Ultra-Linear operation offers the amplifier’s full rated
output power of 60 watts per channel. The user is encouraged to
try both modes and determine their own preference.
WARNING - If the unit has been powered up, you must
turn off the power at the switch and wait at least one hour
before disconnecting the electrical cord. After doing so, the
unit may be unplugged and the top cover removed. This
time is required for dangerous voltages to dissipate.
To switch modes, use a nonconductive screwdriver to flip the 4
switches shown in Figure 2 to the chosen settings. The unit is
shipped from the factory in Ultra-Linear mode.
Caution - Always ensure that all 4 switches are set alike, in
either UL or Triode Mode
MAINTENANCE
The Rogue Tempest has been designed to provide many years of
enjoyable and reliable service. The greatest care has been taken to
select vacuum tubes that provide superior sound and ensure long life.
However, at some point in time, the tubes will wear out. The factory-
installed tubes should last thousands of hours. Should it become
necessary to replace a tube, follow the instructions listed below.
Replace Tubes by :
1) Turn off power at switch.
2) Wait one hour for dangerous voltages to dissipate.
3) Unplug power cord from wall socket.
4) Remove the top cover. See figure 2.
5) Using a glove or clean dry cloth, carefully remove the tubes from
their sockets - DO NOT TOUCH ANY OTHER ELECTRICAL
COMPONENTS.
6) Obtain and insert a new set of tubes. It is recommended that a
new set of tubes be obtained from Rogue. If tubes are obtained
from another source, follow the diagram in figure 3 for tube type.
7) Insert new tubes in sockets using a glove or cloth. See figure 3 for
locations.
No other items in the unit are designed to be user serviceable.
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
