OK, "nothing is impossible!!!" is Adidas ad.
But have U considered the power dissipation in regulator?
Capacitor voltage divider is 'lossless' so there is hardly any dissipation
in dropper.
Anyway we expect Volkov to announce his result.Although his use
of Bipolar instead of MKT is little deviation I think his ckt will work OK.
Best Luck to all who want to use same method. I have constructed
10s of units with such supply and are working OK last 2-3years.
