Sonic Frontiers Power 1 - Installing the Tubes

Installing the Tubes
Be sure the amplifier is OFF (Power Switch Out) before installing any tubes or when any
of the tube sockets are empty.
Wearing the cotton gloves provided with the amplifier when handling tubes will prevent
skin oils from depositing on the glass surface of the tubes. The oils could cause the tubes
to become “gassy” and fail prematurely.
Inspecting the tube boxes that come with the amplifier, you will notice that the boxes
and power tubes themselves are labeled to corresponding sockets also labeled on the
amplifier’s top surface. See Reference Diagrams for further clarification. Insert each tube
in the corresponding socket.
Starting with the 9 pin small signal tubes (the 6922s), pay extra attention to the tube pins
and socket holes for these tubes. You will notice an open space where an imaginary
tenth pin or hole would be. This is for proper tube alignment. Be sure pins are in line
with holes when installing tubes. Gently rock the tube into the socket until the tube is firm-
ly seated. The 6922 tubes are inserted into sockets designated V1 to V3 and V6 to V8.
Note the larger space
between two of the pins and
holes for proper alignment of
tube and socket.
