The peak at 502 for the manual tunes has a lot of noise this last time I ran a manual tune. I have also had to adjust the parameters more every day to get the 69, 219, and 502 to stay at the correct masses. I'm not sure what these symptoms indicate. Any help is much appreciated.
Have you tried thoroughly cleaning the source and replacing the filaments?
