12”x15”… or maybe it’s 15.5”, I will re-measure when I get home.
Two types were used in uprights, mine has the fluorescent light mounted on the tray door so the pan is pretty flat.
The other type of upright has the light above the tray, the front is taller.
Here is a picture of them side by side. I need the one on the right.
BTW if you prefer to do this the other way I can sell you my board. $150 +shipping. It works great, just had K-Lar fix the audio, it got a clean bill of health and plays great. I hate to see a game get trashed.
