Note:
• All capacitors are in μF unless otherwise noted. (p: pF) 50
WV or less are not indicated except for electrolytics and
tantalums.
• All resistors are in Ω and 1/4 W or less unless otherwise
specifi ed.

f
: Internal component.
• 2 : Nonfl ammable resistor.
• 5 : Fusible resistor.
• C : Panel designation.
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
• A : B+ Line.
• B : B– Line.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark
: TUNER
*
: Impossible to measure
• Voltages are taken with VOM (Input impedance 10 M).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.
• Signal path.

* Replacement of IC106, IC107, IC206 and IC207 on
the NETWORK board used in this unit requires a spe-
cial tool.
* Replacement of IC3505 and IC3506 on the D-VIDEO
board used in this unit requires a special tool.
• The voltage and waveform of CSP (chip size package)
cannot be measured, because its lead layout is different
from that of conventional IC.
