Hello all.

I have acquired a pinball table, a Gottlieb Cue Ball Wizard in a bit of a state.

I have fixed the easy things like the bulbs and rubber bands which had basically all perished, however the sound doesn't work.

Theres just a very loud hum/buzz.

I was told to try reseating the sound ROMs and cleaning the connectors and its slightly better. Before you couldn't hear different tones, but now I can hear a different hum when the speech is trying to play.

What can I look at next?

Thanks
