Job has tape and bar reader. The only mag switch is for 77 U (up decel) witch it sees every time. There is no play in stabilizers or slippers. Job is 6 months old. 61 N is inside the bar reader so I'm going to change it out and go from there. I'm thinking maybe electrical noise mabey. So I'm going to reroute the wiring to the bar reader and make sure it's grounded well.

Thanks for quick reply and I will post my results
