[Amps] Crydom Solid State Relays

The power supply of my new amplifier will be using 3 40A Crydom SSR relays, 
One on each leg of the 240VAC and another in one leg to short out the step 
start resistor.  I have been planning on using the SSR's w/o any resistors 
or capacitors across the control connections but I have been advised that I 
should put resistors and capacitors across the control connectors to prevent 
RF from affecting the SSR function and possibly causing "chatter".   I would 
appreciate some feedback from the group.  I don't believe that Jerry 
Pittenger K8RA used anything in the 3CX1500D7 amp that was featured in the 
2006 ARRL Handbook.
