Quoted from Boise_D:I got the altek lamp driver board so I could use regular LEDs. They look fantastic, but the ones closest to the 8 drop targets flicker. I’ve even tried flux bulbs there, and even those flicker. Advice?
Solder a 470 ohm resistor from the base of the lamp socket to the tab. Sometimes in certain games, it’s the only way to get rid of a flickering led. I had to do this with my centaur, after trying three different lamp boards.
