My Broadmoor Eight Track and Radio

This Broadmoor Eight Track Stereophonic Player and Solid State Stereo Reciever, was bought brand new by my dad and has been sitting our garage ever since. The radio is sketchy and you have to play with it to make sure everything is like it should, like the Treble and Bass kicking in and whether or not both speakers are playing. The Cabinet is 45 cm. Width ,stands 11cm Tall, and 27 1/2cm deep. It has two speakers 20cm in width, 25 cm tall, and 13 1/2 deep. Both Speakers are the same size. As far as I know the Eight Track does not work. Like I said, the radio works great and has an amazing sound quality. I don't know what year it was made due to limited information that I can find. That's about it. Thanks for looking and ask questions or if you know anything about it, anything helps
