Sol POWER SUPPLY SECTION II
Position FWB3 (MDA980-l) on power supply subchassis as shown in
drawing on Page X-2. BE SURE NEGATIVE (-) TERMINAL OF
FWB3 is next to transformer. Insert a 6—32 x. ½ binder or
pan head screw from bottom of subchassis, place #6 lockwasher
on screw and secure with 6—32 hex nut.
*( ) Step 34. Connect blue transformer wires to unmarked termi-
nals of FWB3.
*( ) Step 35. Install large (2½”) mounting ring for C9 (54,000
ufd capacitor) on side wall of power supply subchassis as
shown in drawing on Page X-2.
Position ring over the three mounting holes in the side wall
of subchassis so the clamping screw faces the bottom of sub-
chassis and so it will be accessible from the Sol—REG end of
the subchassis. Insert three 6—32 x ½ binder or pan head
screws from outer side of side wall through the mounting
holes. Place #6 lockwasher on each screw and secure with
6-32 hex nut. Figure 2-5 shows an assembled Sol-20 power
supply subchassis.
