Shure Beta 87a Condenser Vocal Microphone - Silver

I am selling my Shure 87A microphone as no longer need it as I have retired from music it has been sitting in the cupboard for a while just before I retired it started to cut out now and then so I stopped using it I never had the time to find out what was wrong with it ? I was told it could be the lead or the mixing desk hence selling it as spares or repair It just might be an easy fix ? not sure ? This microphone according to the paperwork looks like it was made in USA or Germany not China
