Greetings

No data on that point despite review of net. Looked long and hard could find
little of specific detail.  Noted diodes rectifying output of xfrmr have Trr
of 0.1uS.  This provides some guide to max operating freq of the supply.

The ferrite core in the inverter is small and this suggests to me an
operating freq that is high.

Other of more knowledge and experience may draw better conclusions than I
can.
