[QUOTE="handsome, post: 1025501, member: 772"] You should change those 22k resistors across your PSU capacitors to 270k or more. They only need to balance the voltage across the caps. 22k across ~400V passes a lot of current and dissipates more than 1W. I presume you are building according to the Byrth schematic, if so comparing your measurements to the design will tell you if you?ve gone wrong. If building to your own tune (note slyly inserted musical metaphor) then obviously you?ll recognise any disparities. [/QUOTE]
