I dont think the author intended you to use a 220K pot (I have never seen one); more likely a 500K pot set to 220KΩ.

FireAce New Member Oct 4, 2010 #3 Hey Mike, thanks for the reply, except I just realized I used my last 100k pot in my last project, but I do have several 50k's laying around. I dont know how to figure this, but would you?
