Scott, Being a low frequency problem, it sounds like a likely candidate for a common impedance coupling. Possibily through a common ground return. Mind you, if it is Low freq in nature, series inductance [even large amounts ~ 3 mH ect...] and common-mode chokes may not work. Try checking the g

God protect us from committee decisions! Does anyone remember IEC 380 - Great electrical spec but hopeless for any other expect (except topple. Then can IEC 435 which missed flammability. Now we have 950 - which is pretty through but missing a few things... IMAGINE if the selection and de
