Re: [Harp-L] question for the microphone experts



Hi, Bill

That stuff is very common in mics - or I should say "those stuffs". Mfg's used all sorts of glue and goo to seal holes, hold transformers in place, reduce vibration-related fatigue of wiring, etc. In Shure mics alone I have encountered many, many different products. Some are hard like epoxy, others soft like silicone, and then there is more at every point in between. You have to dig it or drill it out but there is no magic bullet - it will depend on the stuff. Sometimes a solvent helps, but rarely. Sometimes heat helps, but rarely. Usually you just choose your weapon of destruction and proceed. Use the least invasive process you think will work. If it isn't enough, there's less chance that you've actually done harm - and you step up to something more aggressive.

Subject: [Harp-L] question for the microphone experts


Hello all,


I have two mic shells that I'd like to start working on and turn into
useable mics.

Each of the mic shells has a black tar-like substance in the back of the
shell, apparently it used to glue or hold something in place. Do any of you
have any idea what this gunk is and how I can get it of there?


thanks,

Bill
