6.5 CONVERSION TO DIFFERENT LINE VOLT AGE. The power supply
can easily be converted from 115-volt to 230-volt input or vice versa
by reconnection of the power-transformer primary, as shown in Figure
2. When making this change, always insert proper-sized fuses. Appro-
priate measures should be taken so that the legend indicates the new
input voltage. On instruments changed from 230 to 115 volts, this sim-
ply means removal of the 230- nameplate; a 115- v
legend is marked
beneath. For instruments changed to 230 volts, a nameplate (Type
5590 -1664) may be ordered from General Radio.
