So im siting in my lab with a jar of whiskey and solder to gather my High voltage power supply ... the PCB is ready, drive`s (all works fine) and stabilizers now mounted but dam!!!! :) the LM 317T gets overheat (circuit total consumes 0.4A only, but its gets hot and my small size HS is not the right stuff ) :)))) tomorrow i must make a good Brass or Copper HS
Maybe some have a good idea for a temperature sensor 4me? :) i wanna a sensor to drive a cooling fan and a small led display of the temperature of the device (maybe two channels one for drives one for power section)
