I'm relatively new to electronics but I'm a quick learner. I bought a bench power supply before I found Dave's videos on youtube so I ended buying the kind he warns about not buying:

It doesnt have a load switch near the output(s), and it has one of those horrible single-turn-pots that make it impossible to tune effectively.
I've been considering modding it to add the load switch since that seems relatively straightforward, but I wasnt sure about changing that pot. Would I be able to just remove the one that's there and replace it with a good quality ten-turn-pot? Or is there some added circuitry/wiring that distinguishes them from the single-turn variety? Most of the images I've seen show them looking identical to single-turn-pots, but I figured I'd ask anyway.
Thoughts? Hints? Suggestions?
