I
came across this old cube type Philips radio/tape player in my garage. It has 4 speakers
inside and architecture that might suit a voice practice amplifier that I could use with my acoustic guitar. I sing a bit low and play
with a pick so the guitar is quite loud drowning out my voice a bit
unless I put a lot of effort in to raise the voice. I stripped
everything out that is no longer needed and I am now left with the
speaker installation. That is 2No at 4w x 8Ώ's
and 2No at 2w x 8Ώ'. It has 240V mains and battery power to the innards amounts to
12volts.
Would a mini car amp (less than €$50) activate the thing and could I rig a mic to such an amp arrangement? https://ibb.co/0DyFQDP - |

For a mic, you´ll need something with a suitable input - and tone control, or a separate mixer. |

And because of the low power handling of the drivers maybe a 2x10w 12v diy amp board (so it can be run off batteries too) and just run a pair of drivers of each of the channels. That should be a simple solution providing you know a smidge about basic electronics.

If it sounds like a gorilla is trying to escape, turn it down.

Maybe I might not have to throw it in the skip.Would some of these off the shelf minis do the trick if I can use the inputs for the mic?

Last one would be the cheapest and by the looks of things tone controls. Just will need a separate Mic preamp stage to be added
