RAMEGOOM's clock mod:
I will post pictures once I get my TZ back together (in the middle of a tear down), but I installed this clock mod last night.
First of all - unbeknownst to me (thought I had an original), my clock had been replaced with a Rottendog board. While I am a huge advocate for RD's Fliptronics and power boards, and the clock mod does a great job fixing the flaws of the clock design.. it just never looked that good.
Well, now that's over. As pictured in the other posts, the light is very full and consistent - and a hell of a lot brighter than the original or RD solutions (full disclosure: I have not spent a lot of time with Ingo's board)
The instructions were far more detailed than is common, and CLEAR. I can't stress how big of a deal that is. Most mods you get a printout with a couple sentences and maybe one picture, but these were very well-written and clear.
The inclusion of the spacers and the extra C-washer were great nice touches that weren't necessary but are a hallmark of a well-thought through process.
If I sound like I'm gushing a bit, I am - Ramegoom also helped me out by sending me a part I needed to test this mod, IN ADDITION to the board itself. Totally worth it, I think - especially if you have put LEDs in the rest of the playfield.
