- New AC power feed -
When i moved my shack to the second floor i also make the AC installation specialy for Radio use. The main AC supply in Sweden is with 3 phase, 380V Phase to other Phase, and 240V One Phase (Live) to 'Zero' or ground.

2006.08.29 Got some problems after i updated the AC Power feed to my shack. The automatic fuse 'blows' every now and then when i turn on my Dentron MLA-2500 Power Amplifier.

Decided to build an 'External' StepStart Module to reduce inrush power when starting the PA. The external unit is preferred in my setup, mainly because there is almost no space to put the unit inside the MLA-2500 PA, also the unit is to stay with me, when or if ever replacing the PA.
