[Elecraft] SP3 intermittent A/B switch

[mjpilgrim]

My apologies if I've overlooked SP3 discussions including this annoying
symptom on mine.  I purchased this SP3 new  a couple years ago.  After a few
weeks i noticed the A/B selector switch had become rather touchy, and at
times the audio would not be present unless I jiggled the switch a few
times.  I sort of migrated away from listening aloud, resorting to my
headphones in order to reduce disruptive noise for the family.  Recently I
decided to listen through the SP3 and was quickly reminded there was a
problem.  in order to listen, I have to periodically jiggle the A/B switch
or activate it back and forth between A and B until finally the audio comes
through clearly.  I swapped inputs from A to B and back again, but nothing
helped.

Am I dealing with a known problem on the SP3, and if so, is there a simple
remedy?  If a new switch is advised, is that available from Elecraft?  I
welcome any helpful suggestions.
Thanks.
Be safe.  73's
