NOTE FOR SCHEMATIC DIAGRAM
WARNING:
Parts indicated by the
z
mark have critical characteristics. Use ONLY replacement parts recommended by the manufacturer.
CAUTION:
Before returning the set to the customer, be sure to carry out either (1) a leakage current check or (2) a line to chassis resistance check. If
the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 460 kohms, the set
is defective.
WARNING:
DO NOT return the set to the customer unless the problem is identified and remedied.
NOTICE:
ALL RESISTANCE VALUES IN OHM. k=1,000 OHM / M=1,000,000 OHM
ALL CAPACITANCE VALUES ARE EXPRESSED IN MICRO FARAD, UNLESS OTHERWISE INDICATED. P INDICATES MICRO-MICRO
FARAD. EACH VOLTAGE AND CURRENT ARE MEASURED AT NO SIGNAL INPUT CONDITION. CIRCUIT AND PARTS ARE SUBJECT
TO CHANGE WITHOUT PRIOR NOTICE.
NOTE FOR PARTS LIST
Parts indicated by "nsp" on this table cannot be supplied.
When ordering a part, make a clear distinction between "1" and "I" (i) to avoid mis-supplying.
A part ordered without specifying its part number can not be supplied.
General-purpose Carbon Chip Resistors are not included are not included in the P.W.Board parts list.
(Refer to the Schematic Diagram for those parts.)
Parts indicated by the z mark have critical characteristics. Use ONLY replacement parts recommended by the manufacturer.
General-purpose Carbon Film Resistor in the P.W.Board parts list. (Refer to the Schematic Diagram for those parts.)
