Thanks all for your help and suggestions - I've been off grid for the last few days. I will look into the dust/contacts issue first, and sweat up on the manual and archive posts in relation to the adjustment procedure. Then I will try to see how far this gets me and report back - watch this spac

Hi If you go back in the archives a few years, there are extensive discussions of the various alignment steps on a 5070A or B. They are a highly recommend read if you are getting ready to dig into one of these counters. Bob > On Jul 3, 2017, at 10:13 AM, Gary Neilson wrote: > > I have a 53
