200V at 10mA

Is there an off the shelf part I can use for the transformer in this?

It's based on a design someone else posted in this group a long time ago (maybe 10 years ago by now).
I can't remember the name of that individual.

Watch out for wrapped lines and character encoding issues for L1, C3, C5
If it doesn't simulate L1 likely has a u symbol issue.
If it doesn't open, line wraps need to be fixed.
