[Collins] Reluctant filter switch on 51J-4 - Solutions?

[Chris Kepus]

My 51J-4 plays and works very nicely with a few odd exceptions: (previously
noted on this list) but the one thing that now concerns me most is the
amount of effort that it takes to switch from one filter position to the
next.  It seems like that small switch lever behind the knob is about to
bend or break every time it finally moves to the next position (regardless
of rotational direction).  Out of concern that the lever might break, I have
stopped using the switch until I have time to pull the unit out of the rack
and examine it.  Is this rotational resistance just one of the switch's
characteristics...or ???.  For those of you who use a 51J-4, is it "easy" to
change filter positions using your filter switch lever or do you feel like
the lever is about to bend or break each time you use it? If the normal
state of affairs is a switch on which the positions can be easily changed,
does anyone have an idea of where I should look for a problem with my switch
mechanism?  If anyone has successfully corrected a similar problem, would
you be kind enough to share your method?

Thanks, 73, Merry Christmas, Happy Honnuka, and Seasons greetings to all!!
