Bill,
I have 2 RS-35M power supplies. When they are powered on, they sometimes
make quite a kick noise as a result of the surge of current to charge the
internal capacitors. This has never hurt anything. The only thing I can
guess for the 720 ohm resistor is that it is there to bleed down the output
voltage when the supply is turned off. I have never heard of anyone doing
this.
