Rogue Audio Tempest Vacuum Tube Integrated Amplifier owner manual Ultra-Linear

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
