Thanks for the feedback. Unfortunately, Harmon has said they don't stock the parts anymore. I did find a service manual online to get info on the 2 capacitors and the choke, which is:
Inductor = choke coll 35uH Ferrite Core 25
Capacitors = CAP,E NP 10uF 100V 20%
I can find similar capacitors on digikey, but have no idea where to look for the choke. It isn't easy to find an 35uH axial choke.
