I have modified the original circuit to peak my interest. My circuit will incorporate (among other things) some AGC and a little more available Speaker Power. But of course, none of this has been tested and therefore operational results may be different than expected.
|My Planned Minima Audio Module|
I will make the first Prototype board with the Toner Transfer Method (TT) to check operations.
Unfortunately, I will be busy the next few days will not have much time to work on this project.
