The swinging choke technique is described in the various amateur radio hand book as helping to stabilise the EHT rail. I would be interested if you could run a simulation on it .
Typical choke is 5 to 20H at 20 to 200mA

Ed,
given that this question is really outside the scope of a strictly "R1155 only" power supply, I will start a new thread for that one once I have a few results. Probably in the "Components and Circuits "section with a cross-reference to this thread.
