I recently traded a pin for Bally's Harlem Globetrotter pin. I installed various LEDs that I had on hand for the back box and GI lights and really brightened up the game. I then ordered the premium non-ghosting LEDs from Cointaker for all the controlled lights in the back box and under the play field. After looking up some parts on Marco Specialties website, I saw the Ultimate Bally & Stern LED lamp drive board. Do I need to buy this as well so the controlled lamps will not flicker? Isn't this the reason for buying non ghosting LEDs? I figure I should get the LEDs in the mail in about a week, but would like to have everything ready for install when I do. I never had a game that required something special for LED installs, not even my former EM. Any help would be appreciated.
