High voltage SMPS

[Johan Potgieter]

Hi all!

I hope I might be excused for some laziness, seeing as how it is this time of the (new) year ..... (and my best wishes for all who read here!)

I would like to try a sm power supply for a tube amplifier, with highest voltage 600V d.c. at 500mA peak, apart from the usual lower voltages. General information is available aplenty; I was hoping someone might have a tried-and-tested design, particularly with obtainable transformer cores and specs. The h.v. winding might require some special precautions. I am using a bridge rectifier, but would have to use sufficiently fast 1,5KV 1A rectifiers. Input will be mains (230V 50Hz over here).

Many thanks!
