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. And with your Rogue Audio amplifier, you can be sure that you are getting the very best in tube amplification.
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. After removing the amplifier from the box and packing material, CAREFULLY turn the unit upon its side. Remove the 4 thumbscrews and washers.
3) Remove the Top Cover - Using a phillips head screwdriver, remove the top cover of the amplifier chassis. See Figure 2. MAINTENANCE The Rogue Eighty-Eight 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.
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.
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 the (-) negative loudspeaker terminals.
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. Note - the amplifier is factory set for 8-ohm speakers. ⇒ Using a 5/16” wrench, remove the outermost nut from the red binding post. ⇒ Remove the wire and lug marked 8 ohm from the binding post.
