: panel designation and adjustment for repair.
• All variable and adjustable resistors have characteristic curve B, unless other-
wise noted.
• As to the voltage volue shown by the semiconductors on the Shematic Dia-
gram, see the another list
• 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.
