Before fitting the backbox light board back into the backbox, i removed the reel assembly brackets and gave the light board a lick of fresh paint to brighten it up a bit. While the score reels were out i gave the mounting brackets an cleanup before refitting them.
One mod i did here was to space the lightboard back a few mm from the glass, by adding aluminium strips to either side where the mounting screws are. the main reason i did this was because the chipboard surrounding the lights had swelled a bit, making it very difficult to remove the backglass as the lift channel on the glass was catching on the chipboard. When i brought the game home i had a hell of a time removing the glass, until i worked out what was stopping it coming out. Eventually i worked out that by loosening the lightboard screws the glass could be safely removed. The aluminium strips fixed problem completely. Also i spaced the reel brackets out closer to the glass, with washers under the mounting screws to compensate for spacing the lightboard back. Moving the lightboard back also spaces the lightbulbs back from the glass, which might help save the backglass paint from heat. I'm also using #47 bulbs behind the glass.
