It's been a long time since my original post, so thought i better give an update.
well have got inside it and replaced 1 of the transformers, thankfully I had a midway pac man spare. Took a while to figure out wiring configuration as it had been chopped about a little but got there in the end. fired it up without the board in and it blew the fuse. I didn't have any slow blow fuses so had put too low a rating in. Installed a 2 amp and all was good monitor powered on.
Have just stripped the cp, marquee and coin door metal work bare as was really bad as you can see from photos. Used acid etch primer and then 2k primer for light blemish filling, wet and dried and has all come up good. Joystick shaft and coin insert and reject button have been sent for chroming. I think they were originally galvanised but though I would give a slight bit of bling to it, hoping they will turn out ok.
The coin doors on these are weird as they have a light stone chip type of effect with a metallic grey finish, so i used a worth stone chip from a distance so i didn't get too much build up then went to Halfords to match up the paint. i am happy with the result, it looks pretty close.
Trying to match colours for artwork on sides to fix the graffiti, from kids like me!! Which will be tomorrows exercise and firing the cab up with the pcb in to see if it is alive. It's like this but worse all over unfortunately.
Think it's gonna be a bit of a bastard to mix the colours to an exact match but I am determined. Sorted the black touch ups today with ultra fine artist brushes (courtesy of Aldi!!) and the guy on Ricks restorations who does the free hand painting detail etc makes it look a lot easier than I found it with my shaky hands!!!
Am after sourcing buttons or springs for buttons as these have rusted and no longer spring, also after a Control panel overlay, if anyone can help as the two I got with it are sub standard. If anyone can point me in the right direction I would greatly appreciate it.
will put up some more photos etc in the next few days.
