Maestro control drag

Jim Member ✭✭
edited May 2020 in Maestro

Im loving my Flex 6400 and Maestro, except for one detail. All of the knobs are extremely loose. By that I mean there is little or no drag or friction when operating the controls making it really east to inadvertently bump the knobs thereby changing settings. Is there any way to increase the drag on the controls?

    Hi Jim, I don't think there is an adjustment.  One thing manufacturers used to do in the old days was to put a thick felt pad behind the controls.  If it is thick enough, (but not so thick that it puts strain on the control) it will induce drag. It would take some experimentation, but could probably be made to work.  The controls on the Flex are encoders, not potentiometers, so care has to be taken not to push or pull them too much in the quest for the right amount of drag.

    these are encoders that are simulating **** behavior.. you may be able to get creative with felt or other solutions.. but it sort of is what it is..  if you come up with a good solution to add some drag either with felt or whatever to give a more legacy radio feel.. please share.

    As Chris mentioned, there are felt washers that you can insert behind the dial. then when you put the dial back on adjust it against the washer.

    Source for vintage radio knob felt washers if you did not want to make your own.  I suspect the knob shafts are not long enough to support very much thickness of felt behind the knob.


    and in Canada
