Putting things together..

I glued the MDF together using professional wood glue. The center picture shows the beginning of the insides of the cabinet. From the top down: audio aplifier controls and the power switch, 3x20W audio amp with a 2x18v transformer, the coin slot mechanism, and the subwoofer at the bottom. The center bottom is about an inch aboce the floor to allow for the sound to escape. On the right wall is a switchin power supply for 5v and 12v DC. Also visible is a relay board for the power sequencing and the sequencer itself based on a PIC12f675 (detailed board picture). I did not stay with this solution, but more about that later.
