Hi Bob:
I have used Crydom SSR relays in AC ON and step start circuits for 15 years
with no special bypassing. No problems at all with this set up.

Subject: [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.
