Note:

All capacitors are in F unless otherwise noted.

All electrolytic capacitors are rated at 50V unless otherwise noted.

All resistors are in ohms.

k= 1000, M= 1000k

Indication of resistance which does not have rating electrical power is as follows.

Pitch: 5 mm

 

Rating electrical power 1/4W (CHIP: 1/10W)

: nonflammable resistor.

¢ : internal component.

: panel designation or adjustment for repair.

All variable and adjustable resistors have characteristic curve B unless otherwise noted.

Readings are taken with a color-bar signal input. no mark : PAL

Readings are taken with a 10 Mdigital multimeter.

Voltage are dc with respect to ground unless otherwise noted.

Voltage variations may be noted due to normal production tolerances.

All voltages are in V.

* : Cannot be measured.

Circled numbers are waveform references.
