Note:
All capacitors are in µF unless otherwise noted.
.
PF: 50 WV or less are not indicated except for electorlytics.
. All electrolytics are in 50 V unless otherwise specified.
. All resistors are in ohms, 1/4 W in resistance, 1/10 W in chip
resistance.
kZ = 100, MZ = 1000 kZ
. : nonflammable resistor.
¢
. : internal component.
. : panel designation, or adjustment for repair.
.
All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
. The "4-1. +B Voltage Check" and "4-2. Protection Circuit (Hold-down
2
circuit) Check" should always be performed when replacing the
following components (marked on the schematic diagram).
