  1. The 6V volt filament is in AC? There is many version of universal psu that have 300V out? there is a version of the psu that has the output to 300V? the universal psu has a 'input to 75V AC and then you go to add to -450V, getting a -510V. you can not modifacare that to have the 300V output? Sorry for the newbie queston!
  2. Thanks kevin, I saw the board psu. there would be a real advantage to duplicate the part of +/- 450V?
