Pro Control Maintinence....

[NCM engineering]

Just recieved this message from one of my editors....
"The main volume control knob on my Pro-controller just fell off. I hear they're loose in the other studios too.

Thanks,

Has anyone else seen this? I know the knob has an allen set screw, but here is the dillema.....The set screw is lower than the top plate of the ProControl. In order to set the knob at the factory heigth, I have to remove the top plate. Is there any danger of having the knob just a bit higher, to avoid sending my unit into the shop for 1+ weeks? I don't want to void the warranty by popping the hood just to re-attach a monitor pot knob.....And factory service and shipping is a huge hassle....
