I can post a pic if you want when I get home(the screws are out of my SE right now), but you NEED to have a plastic adjustment tool for at least one of the controls (maybe more its been a while since I looked)

the one you must have it for, your basicly sticking something in the middle of a HV/HF inductor and adjusting it, with a normal metal screw driver like object you will never get it to adjust right cause of the metal messing with the magnetic feild of the inductor, or if your unlucky it can make the thing your holding onto live with a good "sack punching" force

the rest are normal potentiometers
