Original, untested Wells Gardner K4900 series arcade game 19" CGA (standard resolution) monitor chassis. This chassis has not been tested, we found it in a box of parts from a warehouse cleanout, considering it need a a cap kit and the least and possibly repair.
This is the "intermediate version" of K4900 chassis (we don't know the exact model number), it does have a vertical dampening pot but does not have a vertical position board The part number on the main board is "2061433-040".
Please note: working with monitors involves high voltages and can be dangerous. If you are not familar with monitors we do not recommend installing an item like this.
