I built an OHR-100A last winter with help from my two sons. All listed parts were there. I think I had a capacitor or two left over. I don't recall that choke but I'm almost certain you can solder it in near the end when you get it.
OHR is closed until the end of the year
Email or phone them and they should answer in this situation no matter what something says about them being closed. I emailed them about a different matter recently and they answered immediately.
