A small-value choke ahead of C1 would be very effective at reducing peak current. Whether this might work in your application depends on how much headroom is available for driving the regulator.

Agreed on the single small value choke but it needs to be mentioned that a common mode choke doesn't help reduce ripple or inrush current.

I figured that one out when I looked at the value of this choke.
I have a 10mh 5amp I might try out but it may lower my voltage too much for the Rod Coleman. May need a 22 or 24vac transformer to start out.
