To Use the Power Supply:
➀ Plug the power cord into a well-grounded 107-128 VAC,
60 Hz or 198-242 VAC, 50 Hz outlet. (See label on
rear of unit).
➁ Connect the appropriate output terminals of the power
supply to the circuit. (Connecting wires are not pro-
vided with the supply.)
➂ Turn the HIGH VOLTAGE ADJUST knob fully
counterclockwise.
➃ Flip the ON/OFF switch on the front panel to ON.
The switch will light to show that the power is on.
➄ Turn the HIGH VOLTAGE ADJUST knob to obtain
the desired output. The meter will show the voltage
between the 6 KV output terminals.
➤CAUTION!—HIGH VOLTAGE
The power supply uses two 390 KΩ resistors
which limit the output current to approximately
3mA. Nevertheless:
* Always work with a partner.
* Wear rubber soled shoes.
* Work with one hand only. Keep the other hand
in your pocket or behind your back.

Introduction
The PASCO scientific Model SF-9586 Kilovolt Power
Supply provides regulated DC power from 0 to 6 kilo-
volts. The 6 kilovolt output is center tapped, providing
outputs of 0 to +/-3 kilovolts. In addition, a pair of output
jacks provides 6.3 volts of AC power, which is commonly
used as filament power in electron tube experiments.
➤IMPORTANT:
➀ The 6.3 VAC output is unregulated. If you are
using it to heat the filament in a vacuum tube, we
recommend that you use a current limiting resistor
(1-2 Ω, variable) in series. Measure the voltage at
the filament and adjust the resistance to get the re-
quired voltage.
➁ For an accurate meter reading, always use the
left and right output jacks (6 kV). Use the middle
jack only when your application requires a center-
tapped voltage. (The center tap will be the mid-
point of the output voltage only if equal currents
are drawn from the ±3 kV output jacks.)
