SANYO M7850K Stylish Boombox Bluetooth Mod

Very stylish mini boombox from SANYO. I like this one a lot. The motor for the cassette does not have a speed adjustment unit, so the tape speed with new belt is too fast. But in the long run, it will slow down as aging the rubber belt. I added the Bluetooth 4.0 along with DC isolator that removes the ground-loop noise.

Here is a simple wiring diagram.
