EUW-17 Transistorized Power Supply

The Heathkit model EUW-17 Power Supply was designed to supply low operating voltages
and currents. Its variable output voltage and compact size make it ideal for operating
experimental transistor circuits, both in the laboratory and in the classroom.

NOTE: This unit is not a regulated power supply. It was designed as a low voltage power
source with good filtering and variable output voltage. Since the output resistance
is quite low, small changes in load current do not significantly affect power supply voltage.

CAUTION: The chassis of this instrument is connected to earth ground through the three-wire
line cord. When this instrument is used with other types of units, such as transformerless
equipment, a shock hazard may exist.
