Dope/Goop for Voice Coil repair??
Please respond via email as well as the group if you have an answer...
I have a compression driver VC that has about 2mm of the *lead in* flat copper wire *on the VC former* that has obviously lifted due to *heat*. It is intact and not toasted. I was able to make it flush with a flat tweezers. When lifted, it was probably producing a rub in the gap on some excursions (no real sign of wear, but it was tough centering the vc in the gap with it sticking up, which is how I found it using an eye loupe)... enough story. What I need is a goop/dope that will stand up to high temp, like the original (or better) to lightly coat this little 2-3mm section of conductor and hopefully hold it permanently in place (I won't be over driving these anyway, so it won't get as hot as it probably did in SR application). The questions: - who supplies the vc winders, and what do they use? - is there an off-the-shelf item that would work? (even from Loctite or similar companies) - what sort of stuff is current state-of-the-art, what was used 20 yrs ago? I have access to almost any supplier, but I'm not sure what is out there, who makes it, and which companies are making the stuff. Please don't suggest 5-min epoxy, crazy glue or anything like that - those things won't stand up to even moderate temps... This is a diaphragm that is no longer made, so doing a proper repair is worth the time and effort to acquire the right materials and do it right. (I can UV cure and/or bake, if need be...) TIA, _-_-bear Please REPLY TO: |

You need to contact a professional speaker reconer to get materials that are
made for your specific need. There are many on the internet; all you have to do is find one who is interested in selling materials to a DIY person.
