Be careful not to heat the minus side of tantalum capacitor, because
it is damaged by the heat.
Constants of resistors, capacitors, ICs and etc with XX indicate
that they are not used.
In such cases, the unused circuits may be indicated.
All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.

Circled numbers refer to waveforms.
Voltages are dc between measurement point.
Readings are taken with a color-bar signals on Blu-ray disc.
Readings are taken with a digital multimeter (DC 10M ).
Voltage variations may be noted due to normal production tolerances.
