Vintage Concord MK-8 - Reel to Reel

Description

Vintage Concord MK-8 - Reel to Reel and 8 track machine
For parts or as a show / conversation piece, not working. It turns on and you can get some sound out of it but there’s also a loud buzzing sound. The 8 track player plays back but not well.
The reels spins and seems to function mechanically but the playback is atrocious. A tech that knows how to restore this kind of thing could probably bring it back to life
Missing the reel speed knob
As is
