I was so envious when I played Bungy's Asteroids machine over the weekend. I stepped up to it and hit the one-player, and heard NOTHING until the duh-duh-duh-duh kicked in. It was simply beautiful. I even got one of my highest scores ever on Asteroids while playing it! (24,9xx).

Mine has hummed since I first got it, and I have had to train myself to deal with it.. But now after playing Bungy's, I MUST GET MINE FIXED!

I mentioned to Bungy that someone had said to swap out big blue, and I have not yet done that so I will have to give it a go and see if that fixes the issue. That would rock if it does. I still can't believe how quiet his UR was!!
 
My game also humms and gets progressively worse during game play. I messed with the grounds to the speaker but big blue is the next "hope for easy fix" attempt. Asteroids should not hum.
 
Tell me about it. The Hum drives me nuts. I've even changed out Big Blue and it still hums.

However, I have found that It hums WAY less when I use my Asteroids Deluxe PCB(Modified to work in a regular Asteroids Cab(mines a cocktail), then it does with the original Asteroids board in use.

At first I blamed the AR board, but now that the humming is less with the AD Board than the original(as the AD board is using the same AR as the Asteroids board), it must be something in the actual PCB that is amplifying the hum. Weird.....

I've been following these threads, and the consensus seems to be that if you have good voltages, replace big blue, clean connections, and it still hums, its caps on the mainboard. Do a search, someone fixed theirs.

Imma have to look it up myself, mine hums pretty bad too.

Not only that, but it looks like Bungy did the fix!

I didn't actually replace the caps on my game board, but I did pass that piece of info on to vintagegamer. My Asteroids came without a board so I got one from road.runner. He's really good fixing Atari vector boards and he's real nice to deal with. He probably went over the board real good before he sold it to me.

I did rebuild my AR board and replace Big Blue as a matter of good practice, but I don't recall if it help with the hum at all.

Yep, I've replaced all those caps.(Big Blue, rebuilt the AR and even recapped the Asteroids PCB, all caps, including the ones mentioned here.)

And I still get hum. Must be one of those things. Maybe some board versions act differently then others. Who knows....

Send your boards to road.runner I have a couple of vector boards from him,AD being one of them. No hum and they run great, RRuner is the best!

I agree, I just can't afford his rates right now (his rates are definitely justified, I'm just currently dirt poor)
 
I can tell you that if your voltages are too high coming off the AR board it can hum, and also, I had a bad hum in my AD that turned out to be a bad transistor on the AR. You could tell as the nylon screw bolting it to the heat sink was yellowed vs the other 2.
 
Wish I could claim some magic cure for hum - but other than nice clean power (big blue) and grounding everything metal - I would suspect the AR board
