No I said that if you were going to use a choke that it should be a tuned
choke. There is no way that you will get good dynamic regulation with a
regular choke or a swinging choke in an SSB power supply verses a capacitor
only filter. Static regulation may be fine with a choke but not dynamic

Look again at what Jim Tonne posted and look at his spice model and you will
see the large dip as the load is supplied and the ringing.
Maybe Jim will post the model of the high voltage supply he is working on.
