Just hooked up my monitor that has just been recapped for my dk....and I am getting a constant humming from the speaker. Adjusting the volume does not affect the hum...any ideas why??
 
Did you do a deluxe cap kit which includes the caps you need to replace on the audio board?

Also, speaker hum is really common on Nintendo machines. Obviously, if it's unbearably loud, then you may have more of a problem and from my understanding, it's usually linked to the audio board. But if it's a slight hum that can get drowned out by the game itself, then it's considered "part of the experience." :D

And yes, it's been brought up before and, for the record, my DK has a slight hum and I've gotten used to it.

I did not do the caps....buffett did...and I am pretty sure he did it all. It is not annoying...but "there". U can still hear it from about 6 feet away...
 
Make sure the second anode cable coming out of the CRT is no where near any other cable. Just a thought.

Oh, yeah... don't touch that with your bare hands. :)
 
A DK machine will have a hummm it was a flaw in the board design a balance of half way on the volume pot on the audio board and full up on the 10k variable resistor pot on the DK boardset you should get a decent balance when the digital chip the dac08 and the MB3614 kick in for sounds then the hummm fades out. The design was changed in the DK Junior boardset to eliminate the hummm. So to answer your question yes you will still get a slight hummm sound.

I just brought a game home from Buffet's place and I have never seen so many monitors in one place at one time. While I was there I watched him repair and send out a monitor board in about 20 min.

If buffet did it I am sure he replace them all.
