I feel like an idiot. I’ve looked and looked. I can’t find what eprom is the replacement for the GROM video mask roms on this golden tee 99. It’s 32 pins. Anyone?

I use these for Neck board color pots. They are...
Double check the 3 large transistors on the neck board don’t have cracked solder joints. Common area since they get so hot. Don’t touch the heat straps around the transistors, I believe they have higher voltage on them. Obviously poor connection on the neck itself could be possibility.
It appears all slot stuff including for sale, is posted here.
Super Jackpot Party WMS slot for sale but I’d rather trade. Set up for home use with plenty of credits on it. Can send video if you’d like.

If there’s no adjustment for the 12v, I would think the caps are probably old and out of spec.
I come from an auto repair background. These are the Delphi (now aptiv) tools I found online. The round one has ID of .120 and OD of .129. Not sure if the round one would help for molex but price seems reasonable from this site.

Move the B+ pot see if anything changes. I also would swap the Zener diode with working board if you can. To my understanding a Zener can test good in diode mode, but not be working at its desired voltage. In this case it’s 18 volt Zener
I think common power supplies failures- ic101, ZD101,bad large transformer. I would also flex the pcb with something non conductive in the power supply section, and see if bulb changes. Thus showing bad trace/solder. Maybe @M K L will chime in.
These are from a Satan’s Hallow scan that I cleaned and sectioned off, for visibility sake. I believe these are the same as Tron? Maybe others. @cdjump can you confirm?
