Mic repair?

[Deleted member 337]

I have several mic's most of them are Rk56's and they all need fixing. Does anyone know of a good mic repairman? I know most radio tech's probably don't like fooling with or repairing them but I just can't throw away good money and buy new ones.

Can you consider learning to do it yourself? Out of necessity I've learned to become pretty good fixing D104's and Turner desk mics. I buy them in good looking condition but also they have some one or more electrical or mechanical problems. If I paid someone else to do it I'd lose money for sure. So bit by bit I've learned to do it myself. You might be surprised what you can do if you take it slowly and learn about mics and how they work. A few small screwdrivers, a good ohm meter, a can of contact cleaner spray and a contact cleaning file will go a long way. Next thing you know you'll be fixing your local's stuff besides your own and making even a few more bucks.

Practice soldering, get the wiring diagrams on the internet and dive in. you got nothing to loose and everything to gain. Most of the time a mic problem is just broken soldered wires.

What is wrong with them, cords,elements,switches or transducers?

Most of them just a broken wire or two. I've tried soldering but I just can't get the hang of it. If I could I would. What kind of solder would I have to have? Maybe if I just keep practicing and have more patience maybe I could do it!

Get you some 60/40 rosin core from RatShack. I keep several sizes on hand, but .02"-.03" should work for most mic repair.

Go to Radio Shack or any electronics internet seller or ebay and get a small roll of Silver Bearing electronic solder. It has 2% silver and flows and sticks better and is stronger than regular electrical solder and is a better electrical conductor.

For small wires and connections use no bigger than a 25 watt soldering pencil type iron. Also get these at Radio Shack for $8.95

Many folks go wrong by using too much heat or too large a tip. Use a little skinny "pencil" tip.

Also keep the tip CLEAN as you go along. The resin in the solder will burn onto the tip and will start repelling solder. You see solder pencil stands with a tray in front with a sponge in it. Get sponge wet with tap water and use this to wipe the tip off as you go along. Also can clean tip with sand cloth like "plumber's roll." Can get that at any hardware store.

Tip should stay bright and clean as you go along. Keep applying a little bit of solder to the tip so the tip stays shiny looking like melted solder.

Pretty simple - remember these steps:

Get Silver Bearing Electrical Solder
Not too much heat
Tip no bigger than the job needs
Keep tip clean

You'll do fine

60/40 from radio shack and a cheap 15 watts soldering pencil is all it takes and a little patience.

I wish I had the patience to get this STATIC Echomax 200 going I have here I also have an older Galaxy / Sadelta base mic that needs a new element which I cant find anyone that has them it also needs a new power cord. I miss that mic it was a bit touchy but really had some audio to throw around.

Dontforget to tin/melt some solder on the wire first Itll make it easier to stick to wjere ever your soldering it to.

all good advice,especially the one i quoted from 15 minigrass, tinning is probably THE most important thing to remember when soldering mike wiring.It's also a good idea to tin whatever your connecting the tinned wires too as well.

Ditto!

a good solder joint will be shiny when you are done. If it's dull, you didn't get enough heat and it can (will) fail, usually with temperature changes.

I recently ran across this, I thought it was pretty well done.

YouTube - How and WHY to Solder Correctly

"curious inventor" has some other good vid's.

An option may be contacting the manufacturer, many companies will do whatever it takes to please a customer, even when things were out of warranty I have contacted companies and was pleasantly surprised....
