Hello again, while working on my radio a friend stops by and asked me if I could look at his Turner mic. I said sure, but I cant seem to find any schematic online that uses the LM386N IC. Would anyone happen to have one. Lmk thanks
Found one! ThanksHello again, while working on my radio a friend stops by and asked me if I could look at his Turner mic. I said sure, but I cant seem to find any schematic online that uses the LM386N IC. Would anyone happen to have one. Lmk thanks
Yup, same one I foundLC,
It is here.

Yup, pin 7 to 10uf 25v to ground.Thanks!
Found out something though...
Schematically - it's missing a value in the Pin 7 BYPASS - you just need a cap they recommend a value of 10uF so not sure of the value Turner would use...

But it does give us a direction to go...
The LM386 is pretty simple - so for output you'll need something I found from the CB Tricks site...
The Super Sidekick manual has this as Figure 4 - but there is several questions about IC used and the drawing is not very clear...

A 4000 is a CMOS logic device - so I can only guess at that application - but a 2N4126 is a PNP.
Hope this helps!
Man you are AWESOME!Yup, pin 7 to 10uf 25v to ground.
There is also pin 5 to a .05uf cap to what looks like a 10.0 ohm resistor to ground.
The 4000 chip is an MFC4000B it is a 250mw audio amp, it is a 4 pin device. The MC3360P is the same device in an 8 pin pkg. I am having trouble uploading the spec sheet, a google search should find them.Thanks!
