Hi, I have a 1989 IGT S plus Slot machine on which the LED displays flicker, not so bad that they are hard to read but enough to be annoying. Also stepper motors hum loudly sometimes and sometimes quiver a little between spins. what components would I need to replace? Caps, transformer, etc? Any slot techs out there? Any help would be appreciated. Thanks, Mike

Are you sure the flicker is not just from the display multiplexing? It would be worthwhile to check the filter capacitors in the power supply.
I'd suggest you look at the power supply - sounds like excessive ripple from failed caps, or a failed diode bridge.
