I was thinking about doing some noise reduction on my Paramours, but changed my mind. It wouldn't be hard to do though. The power supply is very basic, so there is a lot of easy improvements you can make. The most obvious are to increase capacitance and to damp the diode switching spikes. Put 0.022uF caps across the diodes, maybe swap diodes to a fast switching type. Replace the electrolytics with larger values, possibly go to a premium brand and maybe add an LC stage with a nice big choke.
