Page 3: Introduction
INTRODUCTION Congratulations on your purchase decision! We at Rogue Audio truly believe that our amplifiers provide the “smartest” value in high-end audio. If you have never owned a vacuum tube amplifier you will be thrilled by the silky-smooth sound and incredible detail that only a tube amplifier can provide. - Page 4 2) Remove Shipping Pallet - The amplifier is shipped attached to a shipping pallet. This 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 items are critical to ensure that no damage occurs in transit.
- Page 5 3) Remove the Top Cover - Using a phillips head screwdriver, remove the top cover of the amplifier chassis. See Figure 2. 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.
- Page 6 4) Install Power Tubes - To avoid damage in transit, the power tubes are shipped in a protective container inside the main shipping container. Carefully unpack the tubes, and using a glove or a clean dry cloth, install the tubes as shown in figure 3. 5) Inspect Input and Driver Tubes - Inspect the remaining tubes to ensure that they are fully seated in their ceramic sockets.
- Page 7 6) Select Mode - The Rogue 88 features a user selectable option of running in either Triode or Ultra-Linear 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.
- Page 8 7) Matching Speaker Impedance - The Rogue 88 provides options for either 4 ohm or 8 ohm speakers. The impedance selected will depend on the speakers used. Consult either the owner’s manual for your speaker or your local dealer for the correct choice. To switch impedance setting, refer to figures 5 and 6.

- Page 10 10) Polarity - The Rogue 88 amplifier is a non-inverting amplifier (positive signal in gives positive signal out) so, for best sound, care should be taken to ensure correct polarity at the speaker terminals. If your preamplifier is also non-inverting, then connect the positive (+) outputs of your power amplifier to the positive (+) terminals of the loudspeakers and the negative (-) outputs to (-) negative loudspeaker terminals.
