I recently became the owner of an old (as in, analog voltage and current displays) 150V 3A Sorensen power supply. 150 volts is cool, I suppose, but its not all that useful or fun to play around with. High current, on the other hand, seems a lot more interesting. So, how similar is the construction of my supply to a lower voltage, higher current model? Would it be possible to mod the supply to supply a higher current? Or is the better alternative to sell this supply and buy some new equipment with the money? Thanks for the advice.
