In Reply to: Power Supply Problems: How to measure a very short duration current surge? posted by rwalton on May 4, 2002 at 17:32:12:
You can use an X2 rated capacitor (about 0.1uF) in series with the resistor (I use a 10 ohm 1 watt) between the hot and neutral mains. This will help slow the inrush current - I do this as described in the AKSA 100wpc amp plans. Makes switch on transients a little nicer to the upstream components. I also prefer not to swith the amp on/off much and leave it on for weeks at a time.
