Hello SMPS builders

This is my last switchmode power supply. I build it with 2 inches toroidal transformer, half bridge topology, 4 IGBT output, optozener regulated (+43/-43VDC), if regulated less it work in +66/-66VDC. SG3525 PWM controller transformer direct drive, buffer less, now, to wait a new-next power amplifier.
Comments are wellcome.
