dear Mr.Well,
Still, i will suggest to check all wires from side board and ion source..
Quad frequency adjustment may also problem..
Otherwise it may electronics problem of power amplifier or side board..
i already checked all wire and all ok
dipping the Quad did not done
this problem happen after electricity cut off from the building while the instrument was running
Check around above pic that any wire is broken or bend, may be brown color..
i checked all wire and removed the black cover to see component of the board and all is ok
Then dipping of quad is only option.
And if still problem then onsite service call need to check electronics..
