You're welcome, and thank you for the comment. I am truly blessed to live in a time where the internet has made it possible for me to see the work of others in real-time. This is how I learned to do this and I'm just trying to give back in some small way to perhaps help inspire others.

Very nice job building the audio Amp. Have you considered using KiCad to design a printed circuit board for non-critical boards like the audio Amp?

kmnl926, yes indeed, using KiCad and other design tools (and having PCB's produced, or etching my own) is definitely on my future to-do list; however, right now I have set a goal for myself to build as much of my rig by hand using Manhattan construction as possible. I guess it's like a cook challenging themselves to bake a cake from scratch vs. using a cake mix. I made some obvious exceptions of course with the display, Arduino and GPS to keep the development effort reasonable.

Hi Rick, Thanks for sharing this. I already started the build. Just a question: how many Watts would you say the 8 ohm speaker needs to be ? I read somewhere that a BD139/BD140 should be good for approx. 3 Watts, so would a 5 Watt speaker be enough ? Can't wait for the completion of the rest of the modules ! 73, Hans PA3CRZ

Hi Hans, Fine Business on you starting your build. I'm not 100% sure what wattage my speaker is, but 5w sounds about right. One thing I did discover is that the quality of the speaker makes a big difference. I'm using an old JBL high fidelity computer speaker unit and it's sounds fantastic when compared to a bare out-in-the-open speaker. You can find this speaker (and other JBL computer speakers) used on ebay for a very good price (e.g. 2 for $18 USD). Go on ebay and search for "304241-001 speaker". Hopes this helps - 73 - Rick - N3FJZ.
