Hello,
Recently I salvaged a transformer out of a variable power supply. The power supply used this multi-tapped transformer to drive a LM317 and depended on the tap it output the relevant output voltage at 1A max.
I yould like to use this transformer (1A) to buils a small versalite PSU for the lab experiments, since 1A is enough for most of the solid state stuff.
I have found this page https://www.edn.com/electronics-blo.../Simple-circuits-reduce-regulator-noise-floor and I have tested the capacitor multiplier circuit with very good results.
Since I would like a clean PSU to be made (for RF experiments), Could you give any suggestions or circuits?
My main concern is what should I do to increase the max current to 1A out of the capacitor rectifier. Any transistors and base resistors suggestions?
My intention is to build multiple regulators, each driven by a separate tap in the transformer, to have a sumultaneously multi-output psu.

Also I have found this regulator http://www.startfetch.com/keantoken/content/Kmultiplier.php
What is your comment about it, is it considered good?
