AC LINE CONNECTIONS FOR OVERSEAS USE
The

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
