Hey Don,
I recently bought myself an AR30 too; and found a couple of references to your Geocities site, which are quite dead ;)
"Here's a spec sheet that I found that apparently came with an AR30:

"I've drawn a simple diagram and taken a photo of the situation. Both can be found here:
http://www.geocities.com/ibzstar/mystery/tone.htm"
Do you have any information on the AR30 somewhere else?
-tnx!-
