Dealing with transformer hum

Liguy, I'm not exactly sure what these electrolytics are of which you speak? Can you recommend a brand or a site I can look up to learn more about these. They sound very promising.

Thanks,

All good thoughts and if they relieve the problem , great , but if all else fails The Ah Offset Killer works very well. I had tranformer hum with a Rotel, then with an Anthem. Ive upgraded to Classe since then and the Classe is dead quiet, but I remember The previous Amps tranformer hum driving me off the wall. If you do a search on google it leads you in the right direction.

There are a couple of things causing transformer hum in my sytem. My RPTV casues a slight amount of hum when turned on, and when my wife is using the blow dryer or curling iron I get a LOT of hum, even though those devices are being used on a completely seperate circuit. I'd be very interested in more info on the "electrolytic" solution as well.

Go to the psaudio web site as they have a interesting product just for hum, it's called the humbuster. Also lots of info on the subject!

Here's an interesting reference to the Nelson Pass comments and a lot of discussion around hum circuits. You may have to join the diy site (which is a pretty cool place) to see the circuits themselves -- there's a link to get to the original posts and, after joining, you can see the attachments. BTW, the scope pictures of dc and transformer saturation at the end is very instructive -- I loved the comment "a 60Hz transformer is basically a big, heavy bad antenna" (that may not be an exact quote).
