PS 503A
VOLTAGE CONDITIONS
WARNING
Dangerous potentials exist at several points throughout this instrument. When the instrument
is operated with the covers removed, do not touch exposed connections or components.
Some transistors have voltages present on their cases. Disconnect the power source before
replacing parts.
The voltages shown on diagram 1 were taken with the PS 503A front panel controls
(knob type) fully counterclockwise. The OUTPUT button was in the ON position. No external load was
connected to the binding post output terminals.
Voltage Conditions. The voltages shown on the diagram were obtained using a digital multimeter
with a 10 MΩ input impedance (TEKTRONIX DM 501 Digital Multimeter or TEKTRONIX 7D13 Digital
Multimeter used with readout equipped, 7000-series oscilloscope).
