Note:
All capacitors are in pF unless otherwise noted.
pF: pF 50WV or less are not indicated except for electrolytic
and tantaiums.
All electrolytics and tantalums are in 50V unless otherwise
specified.
Chips resistors are 1/10W.
All resistors are in ohms.
kQ=10002, MQ=1000KQ
{ie}: nonflammable resistor.
[__]: panel designation, and adjustment for repair.
All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
All voltages are in V.
Voltage are dc with respect to ground unless otherwise noted.
Readings are taken with a 10 MQ digital multimeter.
Readings are taken with a D1 color-bar signal input.
Voltage variations may be noted due to normal production
tolerance.
Circled numbers are waveform references.
