Hi everyone I’m working on a Sony cfs88 boombox , I want to add Bluetooth but keep the radio and tape player, I’m new to fixing and renovating boomboxes but I’m learning all the time, if I connect the audio out to phono /line in the sound is horrendous, I presume it’s going through a pre amp ? How can I get around this problem?can’t seem to find a service manual for it, any help would be appreciated, thanks Ade
