TROUBLESHOOTING
Speaker Hum – If hum can be heard from more than a few inches from the
loudspeaker, there is probably a ground loop. If there is still hum, flip the
grounded/ungrounded switch on the rear panel to ungrounded. If this fails to cure
the hum, call customer service at Rogue Audio for further advice.
Tube will not bias – If the meter provides a reading but the tube will not bias, the
tube is probably bad. If no meter reading can be attained, check the fuse (1/4
Amp fast blow). If the fuse is bad, replace the fuse and then set the bias. If the
bias will not maintain itself and the fuse blows again, the tube should be
replaced.
Bias Meter reading is too high – Check that you do not have two of the bias
switches turned on.
Output sounds distorted - Check the bias on the output tubes to ensure that the
tubes are operating properly.
