A few more bits arrived today (recent eBay purchases).
First up is the speaker and grill. It’s 10cm x 10cm in size (4″) and about 28mm in height, 5W 8 OHM. I may decided to put a larger speaker in to the final build of the cab, but I think this should be fine to start with. The Grill is made of a high impact plastic and roughly 12.5cm in size. This set me back around $9 (which included postage). The only issue I have is the connectors are slightly bigger than those running off the JAMMA harness. So i’m going to have to modify the connector on the harness to get it hooked up.
Secondly is a lock for the cab door. This will go on the front. I will be building something of a custom coin door. The plan is to have most of the cab built into the door, so using a proper coin door is out of the question (I’ve probably mentioned that already). This should do nicely. There are a variety of sizes available – this one is 23mm. It set me back around $5.
