[R-390] Mech Filer/Ohm reading

Jon,

You own an R390/A, you need a copy of the "Hitchhiker Guild To The Galaxy"
Remember "Don't Panic"

Yesterday (every day for the last 40 years) it worked.
Today it does not work.
I only has one thing wrong with it.
That's the way we were taught to approach this monster in school.
Keep your working and its one bad part at a time to find and fix.
More than 1 bad mechanical filter at a time is illogical (as Spock would say)
