· Importance safety notice :
Components
identified
characteristics important for safety.
Furthermore, special parts which have purposes of fire-
retardant (resistors), high-quality sound (capacitors), low-
noise (resistors), etc. are used.
When replacing any of components, be sure to use only
manufacturer´s specified parts shown in the parts list.
· Resistor
Unit of resistance is OHM [Ω] (K=1,000,000).
· Capacitor
Unit of resistance is µF, unless otherwise noted. F=Farad,
pF=Pico-Farad
· Coil
Unit of inductance is H, unless otherwise noted.
· Voltage and Signal lines:
: +B Signal line
: -B Signal line
: CD-DA signal line
