A dead microphone was brought back to life. Model: TAKSTAR SN-58
This microphone was brought to my shop and the complaint was it does not produce any sound. I connected it to my amplifier in the shop, it was completely soundless.
It was not the best microphone but it was a repair job that has to be done.
As you can see, it is a uni-directional microphone and the moment I unscrewed the top shield I could see what inside this microphone.
This is the sound pick up of the microphone. Once I unscrew this top off, look what I saw.
As you can see, the yellow wire was cut off and the moment I touched the blue wire, look what happened.
This microphone was falling apart and needed a lot of work. First, it has to be cleaned, re solder all the cold joints and get everything back in the right order.
I am sure you have seen the metal nut in the photo. This one is connected to the sound pick up on the top of the microphone. Once you take that off, you will get the sound pick up off and you can solder all the wires back on. A lot of people do this mistake because once they re solder all the cables back on, they have to twist the sound pick up back on and that will twist all the wires inside and end up cutting all of them off.
The idea here is to solder everything back on. Put the sound pick head back on, tighten the nut from this side and keep all the wires in good working conditions.
I cleaned it; re soldered all the wires and put everything back the way it was. I connected it to the amplifier and I could hear clear sharp sound coming out of the speaker. It was restored and it was back to life. Mission accomplished.
