Gefell UMT800 Repair

(1/1)

maltesen:
Hi there.

I suspect that my UMT800 has a faulty capsule, but I can't figure out how to dismantle it :o

Does anyone know how to get to the capsule?

Best Regards
Morten

klaus:
Are you sure you want to pass on any MG warranty-legal or goodwill? The company is usually very good at this.
Besides: how do you know the capsule is defective if you cannot even see it, let alone test it?

maltesen:
Hi Klaus.

Thanks for your reply!

At this moment I only suspect that the capsule is  "blown" because of what little I can see through the grill (Looks Curley), the way the sound "breaks down" like breath on a capsule.
And because we've had two other gefells that had the same problem.

The mic. is 20 years old, so I'm not worried about warranty..... I will probably ship it to MG anyway, but I'd like to diagnose a little myself ;-)

Best Regards

klaus:
"curley" or wrinkled diaphragms are not uncommon with MG's PVC capsules (see some previous comments from owners on Gearslutz).

Wrinkling (if indeed that's what you have) usually does not happen with a quality capsule.
But no microphone company will be generous if it detects that the capsule head had been opened and the seal broken. Therefore it is even more a reason to send the mic to MG unopened, and ask for a courtesy capsule replacement.
