Dominic,
Try replacing the STK730-020 with a -030. Higher current, may run
cooler. I have been using -090 to replace almost any in the series,
without any problems. Those do run hot. What normally happens is it
gets hot enough to cause the connections to crack on the board and blow
the regulator. Make sure you clean the heat sink and use new heat
compound. Also, those regulators come with a loop bent in each leg.
Don't straighen them; they are important.
HTH,
