AC LINE CONNECTIONS FOR OVERSEAS USE
The
power transformer supplied in DH-500 amplifiers sold in
multi-voltage transformer is installed. This, the 600
ohm
the USA is intended for 120 volt,
60
Hz operation only. For use
resistors, the mounting hardware, and the alternate line fuse are
in other countries, a multi-voltage transformer is supplied in
supplied in kits which include this transformer.
Export versions, available at higher cost. It has dual tapped
The diagrams below show pictorially and schematically the
primary windings which can be connected in series or parallel
alternative wiring. Only the pertinent wire connections are
combinations for 100, 120, 200, 220 or 240 volt, 50 or 60 Hz
shown. There are other wires connected to the 7-lug terminal
power sources. The connections which are different from the
strip which are unchanged. If the amplifier is to be operated with
standard 120 volt connections described in the kit assembly
line voltages between 200 and 240 volts, a different fan, part
