CONTRAST OF MISCELLANEOUS PARTS 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. Screws adjacent to mark on product are used for disassembly. 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. 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%). 561 560 56 x 101 RD1/4PU 5 6 1 J 47 x 103 473 47k RD1/4PU 4 7 3 J R50 0.5 RN2H R 5 0 K 1R0 1 RS1P 1 R 0 K Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k 562 x 101 5621 RN1/4PC 5 6 2 1 F CONTRAST TABLE A-109/MYXJ, MVXJ, MLXJ, SBDXJ and A-209R/MYXJ are constructed the same except for the following : Ref.
