How many of us can repair a 2017 Buick? BAs are like 58 Buicks. Modern gear is like the 2017 Buick to me. I have a 706 and a Pro II. I send them to pros if they fail, unless it is an obvious issue. Poor eyesight and a shaky hand won't allow me to work on them. Good luck with your 706. 73, Tom W8JWN
