The part number on the front is "H74 a" and it's the big part of the power 
supply in the back.  In front (looking from the side) are 5 "h754" 
modules.  The modules and the console power are attached to the "H74 
a"  Other H74x supplies should work.

Here is the wording on the unit:

Dec Power Supply
H74 a

Caution
AC & DC OUTPUTS ARE PRESENT
WHEN LIGHT IS ON

POWER ON
       (( ))


------------
where (( )) = the light bulb.

System was working recently.....The supply's red indicator light no longer 
comes on, nor do the console lights, though the fans still run.  In the 
meantime I will test with a volt meter and so on, maybe there's a bad 
connection.

Thanks in advance

Bill
