    Hey all!

    Another quick question - anything I can do about a loud power supply? The one in my Dealer's Choice buzzes loud enough to drive you mad. I was told once to smack it with a hammer to de-magnetize it which actually seemed to help for a bit but anytime it warms up it comes back.

    I picked up another power supply cheap but when I received it it was pretty rusted so I'd prefer not to use it - I've already made sure it's tightened to the board and to itself fully

    Quoted from Mikala:

    It’s probably not the power supply, it’s the lock relay.

    It's definitely the power supply - it comes before the game is even turned on by the flipper button

    I've been through every relay and used a stethoscope to confirm

    It was the transformer - I tried everything I could to get it tighter/looser/etc and ended up just swapping a spare I had out of a salvage machine. She's nice and quiet now
