This is a vintage 80's Rhapsody multi-band radio cassette player. Model RY-611. Aka Venture 2959-6 or Radio Shack 12-795.
I cleaned inside out and added Bluetooth receiver. There were 2 problems I encountered. It was mono mode radio, and other one was low voltage.
From a stereo jack to mono input, I used his idea in this video.

Thank him for sharing the great video.
And for the low voltage, I used DC step up module to boost voltage up to 12V. The reason I needed to boost up voltage was, original 6.9V wasn't enough to stable 5V power supply to Bluetooth receiver along with LED.
Also, this time, I used rainbow RGB LED instead of RED color LED. I ordered parts from China so the restoration took me more than a month, however, at the end restoration was successful, and I enjoyed music from this cool looking boombox.
By the way, this radio has MIC input, and a 12V power inlet too, so it will be fun bringing this boombox to camp or outdoor activities. Using this boombox not only for the music, but for microphone speaker. When the batteries are gone, I can use the car charger (12V) instead.
Enjoy!
