Glad you're clicking along, I landed in your state, it's FRIGGIN colder than MI!!!  the upside I landed in a place time forgot, no cell/WIFI for 30miles in ANY direction!!   :icon_biggrin:

Yep, my weather station is reading 44 degrees at this moment. If you don't like the weather in Texas, wait five minutes and it will change.  :icon_biggrin:

Did you drive? What part of the state are you in? Be safe!

Yes, it's been working for several weeks. I would like to add a volume control to it at some point.

Did you clean that board and cruddy wires?
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

I got the cleaning supplies today. I also plan to tidy up the wiring I originally installed.

I decided to create a layout before I get into the board cleaning, see attached. Still working on it, about halfway through the board.

In the case that something breaks, what would be a good way to rebuild this board? -OR- If you had to rebuild this board from scratch how would you do it?

I believe the board is correct in this layout.

Thanks Pete, I did, and If I had my rally car, I woulda, but with the redneck camper, it's all I could do to keep it upright at 75mph  :icon_biggrin:




so did you get volume added yet or are you still playing with computer graphics  :angel

What are your plans for the bottom side of the board?
