In other parts of the build I now have a working Heavy Barrel board (and a broken one

) and I have a proper Happ 15A supply inbound as the crappy generic 11A Samsunsueytronic one I had in there couldn't handle powering both boards at once.
I pulled the broken Heavy Barrel board for now and found that the Ikari worked fine plugged into the Jamma switcher on it's own with the crappy PSU powering it, also the squealing noise was gone from the monitor, so hopefully the new Happ supply will do the job well for both of these boards.
Wired up the coin door.
Fizgig is sending me a replacement LS-30 for my P1 joystick that is a little glitchy, he had a nice one knocking around so he's throwing it my way (Thanks Fizz).
Once the project is finished I'll gather together all the extra bits and pieces in the hope of refurbing them one day, I'll have 3 rotary sticks, 1 slightly biffy Heavy Barrel board, a couple of marquees and some random bezels for the pile 'o pieces box.
