I know this is a different kind of heresy, but I wanted some of that same “spooky” effect and decided to try replacing some of the back GI bulbs in my TAF with purple LEDs. It really worked out well! The area is lit up enough but the throw of the purple bulbs is different and enhanced the artwork in a way I was really happy with. You may consider that too. I prefer not to use incandescents due to the additional power draw and to minimise maintenance, but sometimes you just gotta do it...

One other thing you can try is buying a GIOCD from Herg. You can dial down the brightness of your GI lights, and this may have the same effect. In addition, “showtime!” multiball looks INCREDIBLE, the way the GI dims properly, with no flicker as was intended all along

YES. GIOCD. Also get an LEDOCD while you're at it. To clarify: there are TWO boards: LEDOCD and GIOCD. This is the kind of thing you have to see in person to really 'get' it. GIOCD isn't really a big deal on many games, but it is very important for TAF and TZ. (unless you decide just to do incandescents, and then stay away from these boards, they will blow your game!)

The board is simple to install - unplug 2 plugs from
The PDB, Mount the board, plug those plugs on the new board, one cable from OCD board to PDB, add power, done. Herg also ships them with good settings so don’t even need to program anything

Don’t mess with the decal on the PF, they are hard to find and never match up anyway. You don’t want to risk additional problems.

In fact, DO NOT get a GIOCD if you are keeping incandescent. Not only do you not need it, but the additional power drawn by those bulbs (that’s why they get hot) will blow the board

Freeze it off with an upside down can of compressed air (the way they recommend you remove Mylar) and then use GOO-Gone. NOT GOOF-OFF. Very very different. Regular goo gone is much less caustic. And be prepared to not like what you see :/

Make sure you google some pics of magnet-burned play fields first..
