The HV section is planned as an open loop Steve. It all actually depends
on performance vs cost. A HV regulation of 10% or better should be
sufficient and I'm told 5% will be easy to do with an open loop and
readily available filter caps.
Sorry for the confusion but I'm in the learning stage here on switchers.
All the posts here are being saved and I'll talk to my expert this coming
