[R-390] Mech filter question

[Jack Antonio]

I just woke up one of my R-390As after a long nap, and it appears the
2 kc filter is dead, nothing on the .1, 1 or 2 kc filter positions. Wiring appears
OK.  Filter worked OK last time I used the radio, looks like this was a 
shelf failure.

Question number 1 is this:  are ohmmeter checks on the mech filter input
and output terminals dangerous to the filter?  I checked my ohmmeter on
the Rx1 scale, and into shorted leads, it puts out 50 mA, which seems like
it might be too high for the mech filter. The higher ranges put out less current,
which brings up question number 2:

What should the resistance of the input and output coils be? 

And yes, C-553 has been changed.

Thanks

Jack
