El: I know how the Sony arm works and understand how it is allowed to pivot at the rear i.e. it isn't "anchored" at the rear like the older HK / Rabco motor driven designs. Having said that, even the HK / Rabco has enough "slop" in the arm assembly to allow a certain amount of lee-way should sidewall thrust come into play.
As such, i was trying to keep the discussion somewhat "universal" in scope and not just concentrate on that one specific product. There were many other mechanically driven linear trackers out there and that is what i was talking about. After all, the comment pertaining to "why aren't these designs more common in the industry now if they were so good then" was previously used. I was trying to respond to that and at the same time, keep things current with the comments being made about your Sony. Hard to be both specific and general at the same time without some form of confusion arrising : )
Herman: Maybe the Bose servo-suspension is what you need in your car : ) Sean
