repairing

Greetings,

I have an older, used, "patent pending," Shure 545S Series 2 (pistol grip) microphone, and I'm gradually fixing it, having first reassembled the switch in the handle section.  I do get sound from the mic, but it is a little on the quiet, "hollow," and less low-frequency side.  I'm using it as high-impedance.

Greetings-

I recently bought an older Shure 545 (4-pin Amphenol era) on eBay, and while it works, it sounds a bit of the dog with voice: a greatly diminished low end, and reminiscent of talking through a paper towel tube.

Given there's only three parts to the mic: cartridge, transformed and wiring, it seems eminently repairable (by me), but I have no idea what's wrong with it. So I'm looking for pointers, links or URIs of forums that might help me diagnose the trouble with microphone.

So if you could help, I'd be greatly appreciative!

Hi all, first post here, though I've lurked for quite a while now. I recently saved a handful of mics from the recycling bin, and need a wee bit of assistance with some of them.

Before I begin, I should mention that I am a semi-professional electronics repair tech and I do a lot of work on amps, synths, and recording gear, but not a lot of microphones.

First mic: Sennheiser MD421.

Hey all, i finally got around to fixing my car stereo, which is a 'component' system, where the speakers have separated mid/tweeters and a sub box in the trunk, nothing fancy, stock (radio head unit) power for the mids tweeter, 250w amp for the bass box.

Hello friends,

There is a small (less than one second) of clipped audio in a take I recorded with my band. I've been messing with the file in logic (experimenting with the multipressor, and sample editor, and EQ) and cannot seem to get anywhere.

Here is a 10 second clip that contains the damaged audio. Does anyone have advice for me? It was recorded on a zoom mini recorder and all I have is one track of the stereo wav file in logic.
