I'm revisiting this because I am going to be making a new front panel for my ART-13 power supply and I figure while I have it apart I will give a second thought to the replacement of the LV choke.
I have two questions:
1) Is 10hy sufficient for the supply? Can a 5hy choke be used or is that too little?
2) How much current does the LV circuit of an ART-13 use? Is a 300ma choke sufficient or should one use a 500ma unit?
The schematic for the supply I am using is located here:
