[R-390] Filter Bandwidth Question

[Ed G]

Hi Folks,
     My Capehart 390A is working mostly FB, but I do notice what would appear to be filter loss when I switch down to the .1 filter bandwidth.  All other filter positions seem to be fine with no difference in signal/S-meter readings when going from 16 KC down to 1 KC.  But when I go to .1 KC signal level does drop down noticeably. I thought the 1 and .1 positions used the same mechanical filter, so perhaps the problem is something else (load resistor)?  Any suggestions on what to check?  Thanks!
