GF -

How'd you modify your M+3 for wider audio?

Thanks! :D

As there is no schematic of the amplifier, I did it by studying the PC board and changing a few caps. They actually have a wider response stock than any other Turner (base or mobile) or stock amplified D-104. It responds down to 80hz well from the factory. The only stock CB powermic that goes lower is the 575.
I did the work years ago so I'd have to take it apart to see what I changed.

Docs say the mic goes down to 300hz stock. I found a nice one so I'm going to check it out on a cap modded 29.

It might say 300 but I swept mine and it goes lower.
That manual has the wiring diagram but the amp is depicted as a triangle only and has no detail.
