It is not too difficult to replace these chips. I have done this quite a few
times. 

What to do:  get a good soldering iron (approx 25 watts max)
             cut the pins of the LS373 chips
	     now use the soldering iron and a pair of tweezers (sp?)
             to pull the cut pins one by one from the pc board
             now use a solder sucker (sp?) to suck the old solder from the
             holes.
             put in GOOD ic sockets and solder them to the PCB
             place the new chips

Off course, as with all good PCB soldering, do it fast. Allow time for the
board to cool in between these operations.

The chips: I use 74F373 chips in my Mega 1, but HCT373 should work allright.
Anything but SGS Thomson should work (so I am told)
