Sorry if this question is something that has been covered but I could not find an answer with several searches...
i recently acquired a second hand k87 capsule to replace the bad one in an old u87i that I own.
One thing that I missed when buying it was that there are no leads already attached to the centres of the capsule. It also appears to be lacking the plastic piece that sits on top of the capsule. (see attached picture)
luckily the mic still has all of it's leads still attached and also has the plastic top.
I was wondering if there is any special procedure to follow when replacing a capsule in this state?
Do I Unscrew the old cables from the centre of the old capsule, remove the old capsule from the mic, replace it with the new capsule (soldering any leads that were previously attached to the old capsule, to the new capsule) and then loosen the screws from the centres of the new capsule before placing the screw through the circular piece at the end of the lead and then back into the mic?
How much should one tighten the screw at the centre of the diaphragm? Does the tightness of the screw affect the sound?
What does the plastic above the capsule do?
(visible in this picture http://recordinghacks.com/images/mic_extras/neumann/neumann_
should I remove it from my old capsule and place it on the new one?
Is there any info I should pass on to my stable handed tech before beginning this procedure?
Also, What would you consider the condition of this capsule?
Does it look all original? Is it likely to perform to spec? (the capsule pictured in the attachment, not the link above)
Thank you very much for your time and help in advance... It is much appreciated, Sorry to put so many questions into one post. I am just very nervous about ruining a relatively expensive capsule..
Please let me know if there is any other information that you need.
