Here we go with the final Sennheuser MD421-hack-apart-action.
First thing to do is to remove the sign with the serial number. This leads us to a screw:
Remove the screw and tear the swith/connector thingy out of the body. Watch the cables, they are fixed with silicon and are very short and fragile.
Deep inside the body you will find a nut. This nut attaches the grille/capsule unit to the body. Remove the nut with a 7mm Steckschlüssel (sorry, didn´t find the right word in english, it´s the tool in the picture above). Pull the grille/capsule carefully out of the body, just as far as that you can open the four screws which hold the grille on the capsule. Again cables are fixed with silicon and very short, be careful.
The last of the four screws holds the wiring shield and is fixed with silicon/laquer. Remove all four of them.
Remove the grille.
Another view on the capsule (obviously it´s a different capsule than Volker posted here
. Maybe I should hack a 441 apart, too :roll: )
Opening the switch the hard way. Yes, this is CJ-style :twisted:
On the following pics you can see the halfway opened switch unit. You can go further by removing the tiny bolt at the left end of the unit which I didn´t do.
I hope this helps but I should mention that I did this with a dead mike. I don´t know if it´s not even more dead now. :grin:
