SCHEMATIC DIAGRAM INFORMATION

All capacitors are in µF unless otherwise noted. pF : µµF 50WV or less

are not indicated except for electrolytics and tantalums.

All electrolytics are in 50V unless otherwise speciﬁ ed.

All resistors are in ohms. k=1000, M=1000k

Indication of resistance, which does not have one for rating electrical

power, is as follows: Pitch : 5mm Rating electrical power :

W in resistance,

W and

: nonﬂ ammable resistor.

: fusible resistor.

: internal component.

: panel designation and adjustment for repair.

: earth ground

: earth-chassis

All variable and adjustable resistors have characteristic curve B, unless

otherwise noted.

Readings are taken with a color-bar signal input.

Readings are taken with a 10M digital multimeter.

Voltages are DC with respect to ground unless otherwise noted.

Voltage variations may be noted due to normal production tolerances.

All voltages are in V.

S : Measurement impossibillity.

: B+line.

: B-line.

(Actual measured value may be different).

: signal path. (RF)

Circled numbers are waveform references.
