to be sure the tube pins are centered on the socket's metal contacts. Firmly press the tube into its
socket.
Do NOT twist or force the tube into the socket.
Install the rubber chimneys over the tube. The seam of the chimney must face the fiber panel. The
bottom of the chimney has notches that must fit over the grid connectors near the base of the tube.
The heavy copper strap anode lead connects to the spacer on the center panel with the 6-32 screw
and nut provided. Install the anode spring clip connector on the tube's anode cap.
The top cover should now be installed with the vent holes on side of the cover positioned near the
electrolytics. The vent holes on the top of the cover should be on the right side of the amplifier
(front view). Secure the cover by installing the corner screws first. Install all the screws loosely
until every screw is in place. Tighten the screws after they have all been installed.
Install the fuses and fuse caps on the back of the amplifier. This amplifier uses two 20A fuses for
standard 120 Vac operation. If you wish to operate the amplifier on a line voltage other than 120 V,
the jumpers on the power transformer primary windings must be changed. If the line voltage wiring
is changed, the correct fuses must be installed. See the
TRANSFORMER CONNECTIONS
section on page 15 for more information.
CAUTION:
Always use fast-blow fuses rated at 250 volts or higher. NEVER use standard
automotive fuses or slow-blow fuses.
