I was 4 years old, listening to a record on headphones connected to this rig. Leaned too far back, and caught the 1/4 inch input jack on the headphones right in my fucking eyeball.
Love to spend $3000 in 1980s money to get the sound quality of a modern day $150 pair of headphones. Also, really cool to dedicate a full wall of my house to a series of machines that will be obsolete inside six months. Double plus also too, the music cassette was a garbage medium for a garbage era.
Anyone old enough to remember this can tell you about the day they turned a refrigerator sized cabinet of music into 
this little guy. Absolutely changed my life.
