Was thinking og RIFA PEH 169 or 200 series. But yes the Siemens was very hot back then and I think they still are. But the Aerovox T-power I am using is not to bad eigther! Though they are only rated at 63 voltage wich "only" allow secundary AC to be 2x42VAC (59,xxDC).
What I was wondering was if there would be even the sligthest benefit from adding even more VA (Actually only A)?? As I have space enough for an toroide up to 3000VA rating (standard build).
What is your experience with cobolt?
Have Fun.
