19. The voltage value and waveform are the reference voltage of
this unit measured by DC electronic voltmeter (high impedance)
and oscilloscope on the basis of chassis.
Accordingly, there may arise some error in voltage values and
waveforms depending upon the internal impedance of the
tester or the measuring unit.
* The parenthesized are the values of voltage generated during
playing (Test disc 1 kHz, L + R, O dB), other are voltage
values in stop mode.
20. Important safety notice:
Components identified by A mark have special characteristics
important for safety. When replacing any of these components,
use only manufacturer's specified parts.
: Positive voltage lines and negative voltage lines.
: Audio signal lines.
