2. PCB PARTS LIST
(for A-604R/HE)
NOTES:
¢ Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.
° The /\ mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing,
be sure to use parts of identical designation.
¢ Parts marked by " © " are not always kept in stock. Their delivery time may be longer than usual or they may be unavailable.
* When ordering resistors, first convert resistance values into code form as shown in the following examples.
Ex.1
When there are 2 effective digits (any digit apart from 0), such as 560 ohms and 47k ohms (Tolerance is shown by J = 5%, and K
=10%).
