To reinstall the SCB-68, reverse the order of the steps.
The SCB-68 ships with wire jumpers in the F and G positions, as
Figure 2-1,
SCB-68 Printed Circuit Diagram
, shows. You must remove
the wire jumpers to use the positions. Use a low-wattage soldering iron
(20 to 30 W) when soldering to the SCB-68.
To desolder on the SCB-68, vacuum-type tools work best. Be careful to
avoid damaging the component pads when desoldering. Use only
rosin-core electronic-grade solder, because acid-core solder damages the
printed-circuit device and components.
