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.  Should it become necessary to replace a 
tube, follow the instructions listed below. 

Replace Tubes by : 

1)

 

Turn off power at switch. 

2)

 

Wait one hour for  dangerous voltages to dissipate. 

3)

 

Unplug power cord from wall socket. 

4)

 

Remove the top cover. See figure 2.  

5)

 

Using a glove or clean dry cloth, carefully remove the tubes from 
their sockets - DO NOT TOUCH ANY OTHER ELECTRICAL 
COMPONENTS.  

6)

 

Obtain and insert a new set of tubes. It is recommended that a 
new set of tubes be obtained from Rogue. If tubes are obtained 
from another source, follow the diagram in figure 3 for tube type.  

7)

 

Insert new tubes in sockets using a glove or cloth. See figure 3 for 
locations.  

 
No other items in the unit are designed to be user serviceable

.  

 
 

WARNING - This amplifier uses voltages that could cause 
injury or death. Never open the amplifier while it is 
plugged in, and always wait at least one hour after turning 
the unit off  to unplug and open the unit.  

Lethal

 voltages 

can remain in the electronics after the unit is unplugged. 

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. After doing so, the 
unit may be unplugged and the top cover removed. This 
time is required for dangerous voltages to dissipate.
