AC LINE CONNECTIONS FOR OVERSEAS USE
The power transformer supplied in P505 amplifiers sold in the
USA is intended for 120 volt, 60 Hz operation only. For use in
other countries, a multi-voltage transformer is supplied in
Export versions, available at higher cost. It has dual tapped
primary windings which can be connected in series or parallel
combinations for 100, 120, 200, 220 or 240 volts, 50 or 60 Hz
power lines. The Export version includes an additional terminal
strip to terminate the extra transformer leads. In units supplied
for 200 volt and higher AC lines, the line fuse is a 7 ampere
slo-blo type, and a different fan is installed, along with different
fan controlling power resistors, which are mounted on the
underside of the audio module.
The diagrams below show schematically and pictorially the
alternative wiring for different supply voltages.
