Several people have asked me about this project and what is happening. It is still ongoing...despite some recent personal challenges. So here is a bit of an update:
1. The "AUX" function has been removed and in that place I've adapted a small latching switch and on/off button. The red arrow in the first image below points to this. I didn't figure there would be much interest in the AUX function and this was the best place to locate a switch I could find. Note, please: The switch doesn't control volume. Just on/off. You can see the switch in the second image. I think it will be more convenient than any other option I had.
2. Some of these were sent to me with only small (3 watt) amplifiers. I bought small amp boards that will add twin 40 watt channels and will also operate on 6, 8 or 12 volt and those were added to the sets needing them.
3. A CNC program to cut a speaker mount has been written and hopefully I can test it soon.
Please stay posted.
