With a speaker over 20 years old, I made a Bluetooth speaker with a combination of a Bluetooth module and a T amplifier.
I listen to music every morning before going to work.
Next time, I will connect to the LP and upload the video again.
This is a method that can be easily made in combination with an existing amplifier using a module with a Bluetooth function.
I don't think this method I use is bad.
And the sound is pretty good.
