REPLACEMENT OF PHONO MOTORS
There are four kinds of phono motors and they can be
identified by the marks (no mark, red, black, blue) given at
their bottoms.
When replacing the existing phono motor with the new one,
it is needed to cut off one of the four resistors (R861,
R862, R863, R864) on the microcomputer PWB of the
player, and the resistor to be cut off must have the same
mark as that given for the new phono motor. After the
replacement, it is further needed to add to the micro-
computer PWB the same type of resistor as that which had
been removed when the existing phono motor was used.
