10) Repeat the above steps for each of the tubes in both channels.

As it is a quick operation, the tube bias should be checked on a regular basis. Note that the bias will change slightly on a day to day basis as the wall voltage fluctuates. Constant biasing will wear out the bias potentiometers prematurely so do not adjust the bias unless it is more than 4-5 mA from the correct setting.

TROUBLESHOOTING

Speaker Hum – If hum can be heard from more than a few inches from the loudspeaker, there is probably a ground loop. Be sure to have the amp and all sources plugged into the same outlet if possible. 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 slow 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.
