the ferrofluid arrived today,so after work i got too it.
i was pleasantly surprised to find i didn't have to desolder the voice coil,phew!
interestingly there was still quite a bit of the old fluid still present.
i very carefully lifted off the voice coil and cleaned out the old fluid and re-filled with the new,about 15 mins each tweeter.
happy days!
here's a vid showing my sausage fingers in action!
THE BEST BIT IS THEY STILL BLOODY WORK TOO!!
