Transformer Connections
The power transformer of the AL-800 has fourteen different voltages available on the primary and is
rated at full power with supply frequencies of 50 to 60 Hz and voltages above 100 volts. The
Jumper Connections
chart below indicates the proper placement of jumpers for various
power line voltages.
Jumper Connections
CONNECT A JUMPER FROM THE BOLD COLUMN HEADING LETTER (
"A" - "F"
) TO
THE LETTER OR NUMBER IN THE ROW NEXT TO THE DESIRED "HIGHEST LINE
VOLTAGE".
DANGER:
Never change jumpers with the power cord connected to an outlet.

WARNING:
The AL-800 requires different back panel fuses for various line voltages. Use the fuse listed
in the JUMPER CONNECTIONS chart for maximum protection.
Interconnections
1. Connect the exciter's RF output to the
"RF IN"
connector on the rear of the AL-800 with 50
ohm coax. Use any good quality 50 ohm cable long enough to connect the amplifier to the
exciter. This amplifier connection uses a standard SO-239 female that mates with a PL-259
male connector on the cable.
