Well I have a thread ( http://www.polkaudio.com/forums/showthread.php?p=1118355#post1118355 )in the Electronics section, but maybe here I can get more help.

I was told to contact Ben, but his PM quota is maxxed out!:eek:


Well I got this Adcom GFA 555, it had a broken RCA Jack. I replaced the RCA with goldplated jacks from Parts Express today...

Well there is a loud HUMM when I powered the amp. I need help getting this fixed....

Thanks to all...

    Did it have a hum before you replaced the jack?

    Ground Loop??

    Is the hum in both channels?

    Have you tried another outlet in the house?

    Well when I got it one of the jacks was broken... I played music through the right channel, the left had the Humm. Now both have the humm.

    It's not the outlet, i changed outlets and even conected it to my Paramax power conditioner.
