I have designed a symetrical PSU using LM317, LM337 plus power BJTs. The desired output range is at least 24V-2V @ 6A max. Altough not shown in the schematic, i plan to add power resistors and a rotary switch to provide current limiting. What do you think about it? Is there some better way of limiting current, without high power pots, JFETs and resistors?
