We have a number of TDA2611A 5W amplifier chips at the space and I'd like to build a small 5W audio amplifier and perhaps develop it into a workshop project.
Some examples of its use: -

Some thoughts: -
- it's a dual learning and skill sharing exercise
- The TDA2611A costs about 75p nowadays!
- we would just be gainfully employing them!
- this is a set up to knock down -
- the first design is to see if we can make it work
- I don't expect it to be any good!
- we have plenty of large capacitors at the space
- we also have lots of power transformers that will give us 24V
- also audio transformers for decoupling
- potentiometers for fader
- I'd like to control volume and tone optionally by Arduino
