Default CarlosFM regulated powersupply, change output voltage?

Ok, as said in the subject. If I would like to change the output voltage of this powersupply from 25 to 30 volts what would i do? Sure I want a good result but also a understandable answer...

THANKS!

this is the supply schematic, just scroll down to the end

The best you could do is actually download the datasheet for LM338. There is all you need to know. Besides that the output voltage is set by ((R5/R3)+1)*1.25
