mzoltan@TitiFifi The high capacity is cant eliminate a high frequency noise, what is came from switching power supply. The thoiusand microfarad necessary the low frequncy (tipcally 50-100Hz) noise, what is regulary came from transformer greatz. In switching ps no transformer, but a lot of high frequency nosie.
