No, we had a kick ass tool & die division in my factory, I had it backward engineered and slightly modified, then we updated the motor, controller and the pump that came with the unit. My guy was one of those old school genius mechanics who could make anything and we had all high end precision machinery needed for the job in house. We used to make everything ourselves back then.
I find this fascinating and am curios why no one else has attempted such a project. I mean, the TechDas is a success at $100K. Surely there is an opportunity for someone with the requisite experience to produce something like your AS for considerably less than that. The other thing that intrigues me about the AS is that it seems fairly uncomplicated so that it would be relatively trouble/service free for years and apparently offers outstanding sonics.
