and tantalums.
Y Chip resistors are 1/10W unless otherwise noted.L
kW=1000W, MW=1000kW .
Y Caution when replacing chip parts.
New parts must be attached after removal of chip.
Be careful not to heat the minus side of tantalum
Front side of the lens
capacitor, Because it is damaged by the heat.
Y Some chip part will be indicated as follows.
