why Agilent didnt explain any thing about RFPA IN ANY MANUAL
Because that is service emgineer job to check RF power amplifier...
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..
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
