David,

If you pull gently on the knob outward, it will come off.  Behind it 
is the moon shaped nipple with threads on it.  There is a hex head 
screw that snugs it to the faceplate which you can tighten to 
eliminate the wobble.

a little bit and detatch itself from the mainboard.  There's nothing 
holding it down now, but does anyone know if adding some bolts to 
keep the secure might be a good idea??

When I get back in town, I will check again on the XL.  I know that 
on my regular modules, the potentiometers are secured by the nut.

The HEX nuts are only on the headphone and volume knobs, as that 
circuit board attaches itself to the XX-7 case different than the 
rest of them.  The pots on the 16 knobs seemed pretty secure though, 
I was impressed by them when I took them out last time.

Thanks for the clarification Erik.  I haven't taken the XL apart yet 
like you have. :)

One more thing I forgot to mention.  In almost every case, it's the 
filter cut off knob that gets loose first, as that's what gets the 
most use by the majority of people.  So I wouldn't worry too much if 
it's only your "A" knob that feels looser, mine's the same way.  In 
fact some of my knobs are really stiff (last 4) since I have rarely 
used them. :)

As with all potentiometers, it's always good practice to move them 
through out their whole range every few months, just so that they 
stay nice and clean.  Most modern pots are self-cleaning (I assume 
the XX-7's are the same), and if you move them they will keep the 
contacts cleaner.  

BTW, this applies to analog mixers too.  I rotate all the knobs on my 
Mackie board as part of my monthly studio cleaning and dusting 
proceedure.

Realm is right.  Putting nuts on the 16 knobs is not recommended, or at 
least tightening them down isn't.  The knob board is designed to be held 
in place by internal standoffs.  Adding nuts to tighten down from the 
outside will cause the circuit board to flex (this is a bad thing).  The 
volume, headphone, and power switch board is mounted exclusively by the 
two external nuts, as the board is perpendicular to the front panel.
