Robbie, it has been quite a while since our long conversation about
Ampio recuts and some other things. I promised to send you a copy of
a paper I wrote many years ago about the acoustics of the Ampico A.
As I said then, I would have to find all of it.

Well, I think it is all together now. See the attached MS Word file.
Please read it and let me know your thoughts. If you approve it,
please post it.

[ It's a good discussion, Bob, and I think it builds nicely upon
[ the earlier Ampico technical articles by Dave Saul. -- Robbie
