Greetings all!

Just made my first pin purchase, a JokerZ! In the process of fixing up a few things, and have a few questions if y'all don't mind.

1. Voices - All the music and voices work, but after about 45 minutes of being on, the voices "fade away" (think static noise) and are gone. The music still plays, but you have to turn the machine off for a few hours and the voices are back. Any idea what component this could be?

2. Audio humm. There is a noticeable humm sometimes when the game is played. I've read this game has a fairly unique sound board. Again, any tips would be appreciated.

3. Manual/repair guides - Is there a resource besides this great site you would recommend?

Thanks all!
