1. CONTRAST OF MISCELLANEOUS PARTS
NOTES : ÷ Parts marked by “ NSP ” are generally unavailable because they are not in our Master Spare Parts List.
÷ The
÷ Reference Nos. indicate the pages and Nos. in the service manual for the base model.
÷ When ordering resistors, first convert resistance values into code form as shown in the following examples.
7 CONTRAST TABLE
MJ-D508/SDXJ and KUXJ are constructed the same except for the following:
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.
Ex. 1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by
J = 5%, and K = 10%).

560 Ω = 56 × 10
47k Ω = 47 × 10
= 561................................................... RD1/4PU 5 6 1 J

= 473 .................................................. RD1/4PU 4 7 3 J
0.5 Ω = R50 ...................................................................... RN2H Â 5 0 K
1 Ω = 1R0 ......................................................................... RS1P 1 Â 0 K
Ex. 2 When there are 3 effective digits (such as in high precision metal film resistors).
