Lot of 6x Sony Portable Cassettes TCM-150, TCM323, TCM20DV (2), TCM200DV for parts. Picture only shows 1 of the TCM20DV's but there are 2.
Each has a different problem. One for example works perfectly except wont shut off.
One seems to work find but stutters and probably needs a new belt.
Someone with the time to tinker could probably get 2 or 3 working cassettes out of this group.
