I've been trying to find an image of my first stereo, a Soundesign. Mine looked similar but had an 8 track. Slider controls on the bottom, push buttons and up down switches. It had 2 blue kind of meter things that lit up and pulsated with the sound of the music. I sure would like to see that thing again. The speakers were ribbed..The price is right. Even I have a Soundesign receiver. Blue lights, lot's of knobs, STK module inside.
I have it on display. It's the bottom one.View attachment 775312
You'll be hard pressed to find much info on this - they were lower end systems and I'm guessing not cost effective to get repaired.
Play it, enjoy it for what it is.
Enjoy the music
