Adding Bluetooth audio to an old tape/cd/radio device

Taking an old tape/cd/radio player and adding bluetooth audio module to it.
Just trying it out to see if i find the right place to add bluetooth signal to.
Met a few problems along the way, but learned alot from it.
Bluetooth audio modul is MH-M28

I did same but i added graetz diode to output of transformator and andded step down converter to lower voltage down to 5v and its working. I had broken cd reader on mine (mine is tamachi one) and i just used rgl wires from mainboard to cd reader board and soldered those to bluetooth module. I also had to fix that one of speakers stopped working beacuse it had one channel ic and manufacturer tried to make two channels out of one so i just bridged where those two were seperating and both speakers are working.

I want to buy the MUJI CD player but it has no way to connect to an amplifier. Do you think it would be possible to add an AUX or some way to connect to an amp?
