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,

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
