[time-nuts] HP 5370A Frequency counter Problem(s)

[Bill Janssen]

I got a HP 5370A off of Ebay and although it looks terrible I thought it 
would probably work OK.
But it doesn't :-(  I downloaded the manual and have yet to print it out.

Question;
When doing a self check by feeding the 10 MHz from the back into the 
counter it counts cycles OK
but the last 3 or 4 digits are erratic. I am starting to do as much 
alignment as I can but am
wondering if this is a known problem and if a cure is known.

Anyway I think I paid too much for this box of problems but will 
continue to try to repair.

Any suggestions (on repair only) is appreciated
