Head alignment had to b reset in order to produce a fuller sound spectrum. Peak sound level meters will not run equal, left channel stays weak no matter how head is aligned or what type
cassette was played. Faceplate , dial and pushbutton markings are had to read.
I've had this deck since 1985. My original just wore out and bought this one. It's totally analog so don't expect bells and whistles, but the sound quality is great.
