7.2.1
Power Supply Unit Blockbuster sets
Where detailed information for power supply boards is given in
this manual, the boards should be repaired where possible.
In this manual, detailed board schematics are given for Delta
power supply units (refer to schematics
and
),
where for FSP- and LGIT power supply units the functional
block diagrams are given (refer to
).
In future releases of the manual, more schematics will be
published.
