I've got a used AT803b lav mic (the one that's permanently attached to an AT8531) that needs a replacement capsule. I've searched high and low but can't seem to find anyone that carries just the screw-on mic capsule/module. Any suggestions would be greatly appreciated.

I believe the mic unplugs from the power module - don't have one but the AT site says the mic cable ends in a TA3F plug and the power module has a TB3M input connector. But be that as it may, I doubt you'll find a simple screw-on mic capsule. Why not send it in to Audio Technica for repair? Have you contacted them?

Thanks, Steve. Although I have two others where the mic cable detaches from the power module with a TA3, this one has a permanently attached cable as you can see in the first pic.

Long story short, I got this setup used without testing it. As you can see in the second pic, after unscrewing the top screen I see the entire top capsule is missing. I unscrewed a capsule from one of my other mics and everything tests out fine so I'm just looking for the very top mic module. As you suggested, maybe I'll just contact AT and see how much one would be.

Must be an older model. I hope you got it for a good price, like for free. Missing the capsule is essentially missing the whole microphone.
