AC LINE CONNECTIONS FOR OVERSEAS USE
The power transformer supplied in DH-200 amplifiers
sold in the USA is intended for 120 volt, 60 Hz operation
only. For use in other countries, a multi-voltage transformer
is available at higher cost. It has dual tapped primary wind
ings which can be arranged in various series-parallel com
binations for 100, 110, 120, 200, 220 and 240 volt 50 or 60
cycle lines. The schematic diagram details the wiring com
binations which are represented pictorially here.
Note that a 5-lug terminal strip is required when the
multi-voltage transformer is used. This, and the 100,000
ohm resistor which is sometimes needed to illuminate the
pilot lamp, is supplied in kits which include the special
transformer. If the amplifier is operated with 200 to 240 volt
lines, the 5 amp line fuse which is supplied should be
replaced with a 2-1/2 amp Slo-Blo type fuse.
