International Ac Line Connections - DYNACO MARK VI Instructions For Assembly Operation

The power transformer supplied in the Mark VI may be
connected for 100 volts, 220 volts, or 240 volts AC line, as
well as for the standard 120 volts AC line (the transformer
is wired for 120 volts use unless this manual and the outer
shipping carton are marked either "100 volt" or "240 volt").
The transformer has tapped, dual primary windings. They
are connected in parallel for 100 and 120 volts, and in series
for 220 and 240 volts. The notes to step 11 on page 11, and
steps 4 and 7 on page 17, the sketches on this page, and the

INTERNATIONAL AC LINE CONNECTIONS

schematic on page 12, detail these alternate connections.
The 5 ampere power fuse should be retained when the
amplifier is wired for 100 volts use, but a 2.5 ampere
AGC/3AG fuse should be employed when it is wired for
220 or 240 volts use.
This amplifier may be connected to either 50 or 60 Hz
current.
