Tom,
Fantastic job!
I've owned AR9's since 1978 and still used them today. I rebuilt them a while back and they still sound wonderful.
It was a real pleasure reading your article. And I agree with Pete B, all the technical and inside information made it feel like you were part of the development team!
Your writing skills are top notch also!
I too have downloaded it for my personal storage and use.
By the way, love the picture of the AR9 sideways on the tripod for the testing session.
Thank you again,
John
