Black Hole
Gottlieb, 1981Hi All,
Can anyone confirm if this is the original lense plastic that goes on a BH? I'm restoring this machine and there are a few customizations the previous owner made where I'm not sure if pieces are original vs custom. Currently this machine is running a red LED 4 digit display here that is too dim to shine through this plastic.
thanks!

The score windows on the inner backglass were overlayed with a blue "film" from the factory.
Typically, this film becomes scratched or wears off. Mark Clayton offered replacement film years ago.
Here is a reasonable pic of a normal BG...

The green "lenses" pictured in a prior post were used on System 80A 7-Digit displays (and for Devils Dare, the 6-Digit extra displays).

The 4 digit display on BH is actually in the apron, not the backglass. The backglass ones do look normal and have a much lighter blue. Just a light blue tint on the displays themselves. It is just the apron one that I'm not sure of. From searching around, it looks like there is a blue lense, but mine just seems to be too blue & thick. Here's an example of one.

You can buy a sack of different colored cellophane sheets for only a few bucks and layer them if needed to make it darker or create different tints. I've used them to tint some LEDs.
