Fostex 280 Multitracker Mixer - $300

Fostex 280 multitracker mixer from 1989 w/ Dolby audio; second owner.
Well kept and in great, functional shape.
Powers on, all inputs work.
Will include a new cassette tape with it.
Power cord is attached, undamaged.
There is slight cosmetic damage to the lower left of the plastic casing.
Two of the plastic buttons are missing their covers but are still easily pressed, and some of the knobs/dials are a little stiff from years of non-use.
I gave it a gentle, surface cleaning, could benefit from a deeper clean and re-lubricating of the sliding, plastic dials.
No box or manual.
$300 OBO downtown Mount Shasta.
