MAINTENANCE

The Rogue M-120 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 tube cage.

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.
