Turner plus 3B mic diagram


Zman, Are you looking for the wiring color code or the schematic for the internal circuit board layout?
 
Here's Turner 3B to 4pin Cobra plus wire i.d.

1) Shield & Red
2) White - Audio
3) Blue - TX
4)Black - RX

Yellow - no connection
 
Hi all I'm looking for a schematic for the plus 3B prefeebly with part numbers .manly the transistors . Have a plus 3b no audio out or ai little dosent register. But when I inject a signal I get 100 percent born hook up a condenser . But not with original element or other pairs I have
 
Between the two of these, you should be able to figure it out.

Good Luck.

Sounds like the mic element is bad. I have several with the same condition. Hook a oscilloscope across the element connections and see if you have a signal when you talk into it, or even scratch across the front of the mic.

Tried different elements no change.. When I do the condenser I get audio but not strong as it should be.. I had a transistor 2n3219 with a broken leg and the 47k risistor was cracked.. I repaces both it with parts but no change something else down the line might have gone bad. Got to dig deeper .. Thank.For the reply
 
Here's where a 'scope is your best friend. Seeing what comes out of the cartridge would be the starting point. If it's working, looking at the output of the JFET would be next.

No substitute for having a way to see where the parade comes to a stop.
