[Amps] Solid state relays and step start

Has anyone had problems using a solid state relay to short out the step
start resistor in a power supply?

I have heard of problems of not enough current thru the SS relays (when amp
is in standby) when used as the primary on/off relay. Sometimes a resistor
has to be placed in parallel with the transformer primary so the relay works
properly.

When used in a step start circuit the current could be quite low as well as
the voltage at the relay due to the resistor across the relay.  Any issues
here?
