Unpacking Instructions
Remove the 3-500Z tube from its shipping carton. Carefully inspect the tube for visible damage.
Look for bent or broken pins. Roll the tube over slowly while listening and watching for loose
internal materials. Be sure the anode is not off center at the end away from the anode connector.
Contact either your Ameritron dealer or Ameritron immediately if any damage exists.
Carefully lift the amplifier from the shipping carton, and place it on a firm, level surface. Inspect
the amplifier for shipping damage. Contact either your Ameritron dealer or Ameritron
immediately if any damage exists. Remove the cover screws with a #2 Phillips screwdriver.
Save the screws to re-secure the cover. Carefully lift the rear of the cover while sliding the cover
back.
The AL-80B is shipped with the fuses and fuse caps packed inside the amplifier.
Additional screws will be included in the fuse pack if they are required.
WARNING: Never remove the cover while this amplifier is connected to the power
mains! Contact with the voltages in this amplifier can be fatal.
The tube must be installed in its socket prior to operation. Observe the pin configuration on the
tube and the socket. One of the pins is separated by a large space from the other four pins.
Carefully observe the pin alignment to be sure the tube pins are centered on the socket's holes.
Firmly press the tube into the socket.
Do NOT twist or force the tube into the socket.
Install the anode connector on the tube's anode terminal and secure it with the screw provided.
Snug the screw enough to secure the anode connector. Do not over-tighten the screw.
Install the fuses and fuse caps on the back of the amplifier. This amplifier uses two 20A fuses
for standard 120 Vac operation (models B and BY) or two 10A fuses for 240 Vac operation
(model BX only). If you wish to operate the amplifier on a line voltage other than 120 Vac, the
jumpers on the power transformer primary windings must be changed. If the primary wiring is
changed, the correct fuses must be installed. See the "Transformer Connections" section on page
12 for more information.
CAUTION
: Always use fast-blow fuses rated at 250 Vac or higher. NEVER use standard
automotive glass fuses or slow-blow fuses.
The top cover should now be installed with the side ventilation holes positioned on the left (front
view). The ventilation 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.
Note: Save all packing materials for future shipping. The packing materials used to ship this
amplifier are specially designed to prevent damage. Replacement packing materials
may be purchased from Ameritron if original packing materials are unavailable.
Ameritron will NOT be responsible for re-shipping damage due to improper packing.
