Anyone here have a Aladdin XT Plus 2 or Advance modchip? (Official one, not clone without traces,there's a difference) , i've got a official chip here and its got the traces to the pinouts but there's no Trimmer potentiometer , so i'm going to add one, but i don't know the resistance increment 5k-20k? I mean would it matter or what. My reason for doing such is i'm going to solder this trim pot to a chip without one. So i can get a contrast adjustment to my LCD.
