Symbol indicates a resistor.
No differentiation is made between chip resistors and
discrete resistors.
NOTE :
Symbol indicates a capacitor.
No differentiation is made between chip capacitors and
discrete capacitors.
k found on some component parts indicates
nce of the safety factor of the part.
when replacing, be sure to use parts of
signation. ATUNER AMP UNIT
